It needs to have a screen.
Perhaps resembling this?
There wouldn't be a screen for 15 usd ... it would have status leds but no screen. Is this for the issue that it could be signing a transaction that isn't the one you think it is ?

I would like to gauge the response to a side project I'm looking at doing - it's basically a very cheap store of your private key (potentially internally generated) which just signs transactions, ie you plug it into the USB of your pc, send it over a txn, it signs it and sends it back. It can also just output the public key as a pseudo-usb-keyboard device if you want to type that into other apps etc.
Now there is a little bit more to it than that, but what it can do is potentially replace the "2nd pc" problem that you can have when you use things like armory etc etc - you don't need to boot up or keep that 2nd pc in a safe, just a small credit card sized device (which is obviously a bit thicker as it has the usb ports mounted on it, as well as a few leds, touch interface etc) .
If you are all willing to pay 60 usd + for a hardware wallet, then perhaps it's best just to wait for the others to mature, but if you are after something cheap, then this could be ideal.
I was thinking that it could also solve the "sell btc on ebay" issue as well as it could be configured that it is "used" once a transaction is signed on the device, thus demonstrating that if someone returned it as "defective" they have, in fact, used it. So you'd ship the device on ebay "charged" with the amount of btc they have bought, prove delivery as its something physical and prove they've used it (which may help with chargebacks etc etc). As it's so cheap, you can just factor the price in with the cost of the sale or offer a refundable deposit if they returned it.
I'll see if I can knock up a youtube video over the next week.
