S3 is The Man at present.  I'd love a Yukon, but UK Finance ain't that great.

I like Coincraft Toys as well:

That's close to 1TH per USD, and you'll be able to mine more than 1 pool at once if it's like my one ( I have a 700GH one. The beauty with these is you can slap 'em up full to get some BTC in, and then dial them back later in life ).  I paid £800 for a 700GH one and do not feel ripped off.  That is about $1100 though ( in the UK VAT is added ).  That Europe Price may well be ok for you.

Anything Butterfly or BlockErupter, in my experience, should be avoided ( as the power consumption is high for such a low hash ).  Anything with Avalon written on it is also behind the curve I'm afraid.


Bitmain and Coincraft seem to be my go-to's at present, although there is a Scrypt-miner about to go VERY cheaply I may have to snaffle...

Basically you check the power consumption vs GH.  If it's 1w per GH or less you're in.  And if it's £1 per GH you should do ok on it paying for itself.  The CoinCraft Desk I showed when whacked up is 0.9 w per GH, but it can be dialed back with time ( so will run at a profit for longer ).  In power-save mode it has the same profile as the s3 near enough ( ~1.05 GH / w ). Depends on what you pay for Electricity really.

Yes, electricity.  If you get a great price then 0.9 w / GH will be fine.  If your prices are harsh you'll only be able to use an s3 really.  I get good prices here, hence my liking of CoinCraft.  I can afford the 0.9 w / GH when I whack it up full.


That should get you going in the right direction.

You might find an old Terraminer going hella cheap, but you need to be careful.  They're selling it for a reason, so odds are it's on it's way out.  KnC Miner are not performing well last I read either.  Beware of Second Hand, but also beware of New.  You have to check the power factor as well as the price.
