For a cheap tire, the Sumitomo HTR's tend to get very favorable reviews from customers I know that have put them on their cars. Our dealer stocks them and I always hear "really good for how cheap they are!" from people. The reviews on TireRack seem to say the same thing.
Not sure of your financial situation but I'm by no means well off and I make my tire purchases a priority, you don't want to go TOO cheap, they're the most important thing on your vehicle. (At the very least, avoid any Chinese tire!)
