Not clear whether $500 is the budget for the bow only, bow + accessories (site, arrow rest, etc), or for everything (i.e., arrows, broadheads, case). But, keep an eye on the big-box stores as well (Basspro, Gander, Cabelas), they usually have some packages within your budget. Also, Diick's Sporting Goods tends to clearance stuff this time of year if you have one near you. I bought used off Ebay about 5 years ago, and still have (and love) the bow (Hoyt Trykon).
