i am looking to buy entropy device that can generate paper wallets.
pm me if you have one

I got one of these but lacked a printer with a suitable usb port so it's never been used. I should dust it off and try again.
IMHO if you create private keys for others you better not fuck this up. So for max security I would use a true rng to generate those.
So whith mycelium entropy you don't have to worry about the randomness of your rng.

bitaddress.org is fine but you should do something along the lines of right click/save page as to desktop. then move the file on a brand new fresh usb drive to a computer that hasnt been hooked up to the internet. you are still able to draw and type to create the RNG values. then you just have to worry about your printer haha.

Oh so Mycellium is just a brand/type of "entropy device"?
Yes.. indeed.
They are best known for their BTC wallet that you can find here: https://wallet.mycelium.com/
They do have other projects as well: https://mycelium.com/index.html
isn't it just as easy to save the bitaddress.org webpage to your desktop, sign offline, and then print via non wireless connection?
Best practise states that creation of private keys are done on a computer that has never and will never, see any network during its life as a Keymaker. This also goes for the printer used to print out the keys.

This is correct.
If you want to be "safe" you can get a cheap or old laptop, remove any wifi cards from it or network functionality (as in remove the actual wifi card).
Wipe the hard drive or put in a fresh one.
You have a few options to either download and install an offline program like bitaddress (via a usb stick) , or run a program like bitaddress off a new or clean usb stick.
Find and buy a laser printer with no network functionality, meaning no wifi, no network cable, - usb only. (wasn't as easy as you'd think with all of todays wireless crap built in , out there)
Connect your non networked laser printer via usb to your "air gapped" laptop (no network connections to the internet or otherwise)
Run the program of your choice, and send the output to your laser printer.
Now you have generated an offline paper wallet which you can laminate if you wish or store safely as cold storage.
If anyone finds that paper, which will in most circumstances have the private key on it, which is usually next to the QR code and public key, they can simply use it to claim the funds.
So keep this in a secure place you wouldn't want anyone to find.
There are many other ways to accomplish the end result , this is simply one of them.
I hope that may help someone looking to set something like this up in a secure manner.
thanks!
Yep did exactly that with a new laptop and printer just for offline wallets. But did not physically remove the wifi card. I disabled the wifi from connecting to anything at all. Also BIP encrypted your wallet so in case anyone does find it they will have a hard time figuring out the password!
Even if you generate your private keys offline it is insecure if you use an unreliable rng. So you need true random numbers for max security which is where mycelium entropy kicks in. The Initial state of SRAM cells when switched on is truly random. Another truly random process for example is atomic radiation.
So the bitaddress generator not any good then? Thats all i got since i do not have a mycelium entry

Interesting input everyone it’s appreciated! Looks like it’s time for me to get a second laptop/printer.

Thanks MJ.>I will look into them
ChibitCty >> I have been using their Mycellium android wallet for awhile. The best I have found IMO for my cell!

Thx MJ. Again once I start to feel like I know a thing or two I find something (entropy device) I'd never heard of b4. They are cool..but isn't it just as easy to save the bitaddress.org webpage to your desktop, sign offline, and then print via non wireless connection?

Mycellium would be a nice as a collectable...but any entropy device that can generate secure paper wallets would be good too.

That's good to know..Thanks Viz 
There were 2 made.
The crowdfunded one and the production one
Indiegogo here - https://www.indiegogo.com/projects/mycelium-entropy#/ Looks like about 550-600 made
The latter is here - https://mycelium.com/mycelium-entropy.html
I (helped) fund it and managed to snag one of the original of that campaign. It will be interesting to see if any of these come to market as I haven't seen them often.
