I'm looking to move my site to either a dedicated server, or a low density hosting provider. Does anyone have a good experiences to share concerning a low density hosting provider?

I'm currently considering using rackspace for a dedicated solution, since there have been some nice and positive comments here.

I may sound crazy to most people here, but I have a personal preference for a Win2K host, since I'm more experienced and comfortable with Win2K. (perhaps I could be talked into a UNIX host, but would need to dig out my old UNIX for dummies manual...)
