Once you get in the under $10 vps offerings it's highly hit or miss. After all, this is the you get what you pay for price range. At $5/mo DO's offering is roughly on par with what you get from Linode or the former Slicehost. This is what makes them special IMO. I'm always evaluating $2 and $3 offerings from lowendbox and so 90% of them suck. Plus I would only trust those for use as backup servers and wouldn't bring them near anything that needs reliability.
