I currently rent a server from ColoStore (in Indiana), and I've been really happy with the service there. Pricing is very favorable, and support has been great on the few occasions that I've needed them. There's been a couple blips in network connectivity lately with Level(3) that's caused me a few minutes of downtime, but I believe they are currently working on bringing in additional carriers to diversify their connectivity a bit more. Overall I would consider them to provide the best value (pure bang/buck) of all the places I rent servers from today. From a colo standpoint, they were one of handful of places that didn't immediately give me sticker shock with their 1-2U colo pricing.
