@Hans, I think that this is a bit harsh. After all those are very cheap hosting solutions. You cannot expect to get premium hosting for $3-4.
In what way am I harsh? There is one evil company out there trying to get a large part of the market for little money. If you don't believe me, just look around WebHostingTalk.com. The Web Hosting section there looks like an anti-EIG circle jerk sometimes.
Examples of hosts known for providing better services:
Stablehost provides pretty decent hosting for only $4 per month. You don't need to break the bank to have reliable hosting for one site.
