Two that I can think of right off the top of my head are the Hoyt Ultrasport, and the Parker Hunter Mag. Both are under 400 dollars and pretty forgiving designs. I like the hoyt ultra sport so much that if I wouldn't have bought my bowtech I would have went with that bow instead of any of the more expensive Hoyts. You could also look at the reflex line. They are pretty much the same thing as hoyt (made by hoyt, with the same cams), just a bit cheaper in some instances.

There are many others and I'm sure you will get others opinions. Those are my two top picks though. You can get the hunter mag in package as well, comes with a sight, rest, arrows and a release, other stuff too. I think the whole package retails for around 400 some dollars. I haven't looked at them lately, but I'm sure it's under 500 bucks.

Good luck,
Paul
