I'd be looking at used bows if I were you. I almost bought a mathews MQ32 for under 400 bucks when I got my bowtech. And it came with sights, a sling, Muzzy drop away rest, quiver and some other stuff. You would most likely still need the release and arrows. Don't forget a target if you don't belong to a club where you can shoot. A simple hay bail will not work with these newer bows. The arrows zip right thru them.
Getting into archery the first time can be a bit expensive, especially if you want to go modern.
Most of the inexpensive bows I suggest to people are still in the 3 to 4 hundred dollar range.
Parker has a package that comes with a hunter mag, a completely set up bow, some arrows and a release. I think it retails for around $450 or so.
I'm sure there are cheaper, but I haven't personally looked at any. I still think a good used bow would be your best bang for the buck for around 300 some dollars. You can find some older bows pretty cheap. Like around $100 or $150 dollars. They might not be the newest greatest technology, but niether will a new one for 2 or 3 hundred dollars either.
Frank would be the guy listen or talk to (above post), I think he has sold more bows in the time I have known him than some of my local pro shops have!
The most important part is making sure the bow fits you and you have some sort of support from the person you get it from. Getting one off from ebay may be a great deal, or may end up being a waste of money if you can't get it to fit you find any one that can help you get it set up and tuned.
If you live near a Cabela's hitting the bargain cave may not be a bad idea either.
Good luck,
Paul
