Buy four A2 Terminator miners ($800 to $900 each USD). They have everything in one solid box.
Otherwise - for better energy efficiency - go with the KNC Titans -- but beware of the current issues.

Saw this first thing came to mind was you, so posting it.
nice price or make a offer, he takes offers, with free shipping for a A2 110 MH with PSU,the PSU looks like a sea sonic, i have two sea sonic gold 850, I got a good deal on Amaze for two the other day. they are really good PSU = to Corsair or VGA , so that's a 150 or SO right there, you may even be able to buy one without a PSU . i would ask if you have your own PSU or can get a better one for less .
.
I'm broke atm or i would buy it .
@ Borgminer
He's right A2's are your best bet right now. The 200-225MH/s AlcheMiner Scrypt ASIC Miner comes without PSU's, you need 2 to run it, are nice, you can find sweet deals on them, but if you don't want to rewire your house or run one or two 240 lines to run a few and 110/120 lines are poss , but not wise.
I'd hold off on buying them till they get the power usage under control more. I was temped two weeks ago when I saw one going to for $ 999 all most bought it, had the cash then , but the power usage is to much for me + I would have to put out another 210 for PSUs . or USE server PSUs
and i know spartak advice against but mining is very profitable if you have the power costs below 10 cents per KWH and have the hash and the room in your home, which i do, you won't get rich but will make some nice change, can even make living doing it, i know a few on the forums who do and have told me they do.
my thought i never advice against it no disrespect spartak maybe in two years i wouldn't home mine or would, but it's like anything you have to keep up with it , if your are going to do it.
Look at this to
https://scrypt.ccI built it up to 57 MH so far i started with 1 MH I keep buying more Hash investing it back in to hash till it reach say 100 to 200 MH then start taking the coin and hope the OP running it doesn't skip before i get something worth while out of it. , this is to me how all cloud mining of this nature should be done not how Zeus etc do it .
Diff is dropping a tiny bit in 7.6 days or less, may drop more , bit coins are holding at 240 or so .
