I've used and recommended CrystalTech for years to my clients, which initially drew me into this article. It's quite a discussion on the current issue of rent vs buy (er....buy and rent rack space) with regards to web hosting. The post itself is not anything special (sorry, Jeff!) due to it being a very common dialogue between any team evaluating new hardware. However, the discussion that follows offer a number of tips and recommendation on today's breed of web hosts.
