I'm currently running a dedicated server with LayeredTech, and I'm looking to switch to my own server to avoid HW upgrade fees and such. I'm looking for about .5mbps of good bandwidth in and around the South Bay Area with 1U of rackspace.
I definitely recommend Layer42. Their owner, Steve, is a real stand-up guy, I used to work with him. I toured their new Santa Clara datacenter recently, and it's awesome. An old Colo.com facility. Steve doesn't play the kind of games that 365main, 200paul, etc plays. His pricing is straight forward, and his service is excellent.
