I'm in the process of renting a server from them. It will be arriving at the DC on Wednesday and they told me it would be configured and delivered on Thursday. If you would like some comment and can wait till then, I'll gladly give you some. Have sent them a number of sales emails, always got a promt response. Also have a contract with them, so in my eyes that proves they're 'on the level'.
Server hardware is Dell, so can't complain about that. Transfer is pure Level3. Not sure if they have a backup provider, but I don't really care. Level3 is excellent bandwidth and I can't imagine there beeing much downtime with Level3 bandwidth in a Level3 datacenter.
Got some good pricing out of them. Not the cheapest you'll find, but still very competative seeing it's not Cogent bandwidth and it's prime quality hardware.
