If you're interested in scrypt mining, take a look at Progressive Altcoin Mining as they are selling cloud based mining plans for when the ASIC hardware hits the market.
http://www.progressivealtcoinmining.com/?ref=PAU2038They are the same group who run Progressive BTC Mining since late 2012 and they've done everything they said they would and have been very helpful and responsive to questions and whatnot. I've been a PBM member since Nov 2012 and ive been very happy, and in the spirit of being open, i've been helping them build the PBM website and also the new PAM site.
The sites aren't wonderful, but its effective and informative. The new PAM site is still a WIP though, but its coming along nicely and once a few bits & pieces are sorted then members will be able to access their account and verify everything (emails confirming the purchase and user info are sent too).
Their forum is helpful too, and only spam post have ever been deleted (i have admin rights, so i can tell), we've never had customers complain or even argue, which i think speaks to the way the bitcoin project has been run. The Altcoin site uses a much less complicated solution, working on the sale of a fixed hashrate, compared to PBM which took far too much effort to explain (to the extent im not bothering in a PAM site, but feel free to look).
They also have a referral bonus, so if you're interested please use my referral code. There is a 5% bonus for using the referral, which goes to both parties, so if you purchase a 1Mh/s 1 year plan, then you'll receive 1.05Mh/s, and i'll get a bonus of 0.05Mh/s also.
The referral is tied to the url, so use it, dont use it. But we'll both get a small bonus if you do.
