I have been using the rackforce.com $59/month Windows 2003 VPS and very happy with it. System is very responsive (they are using Microsoft Virtual Server as the platform, which means you get a true virtual server, with fully dedicated RAM). I am migrating to a dedicated server at ThePlanet this summer for other reasons, but I would highly recommend rackforce.com for a VPS.
Prior to that I had godaddy VPS for a little while. Customer support was great, but the server was unpredictable in its responsiveness. My logs showed occasional 3-4 second lags from the time I place an order to the time it was sent (the machine must have been trashing like hell). I suggest you stay away from any hosting packages that use the Virtuozzo platform - it helps reduce the cost, and works OK for web hosting, but the occasional slow downs might hurt your ATS.
