It's good to see some fellow bowhunters (and target shooters here. I have been bowhunting for 7 years now. I have taken quite a few white-tailed deer with archery tackle, including one buck that made the Pope&Young record book.
Thebeekeeper1, I guess I am like your brother--I bought a new $1300 bow last year. It is a PSE Intrigue. All carbon, weighs only 3 lbs, 6 ozs loaded. Quite a treat to carry in the woods.
Targetshooter2, nice bucks.
Garandman, the best thing you can do is to be fitted at an archery shop BEFORE you buy a bow, new or used. Find out your draw length and a draw weight that you are comfortable with. If you can't draw it comfortably while seated, it is too high a poundage. Don't get caught up in the "if you can't pull 80 pounds, you are a pu***" belief. I am 6-foot, 170# and I shoot 61 pounds. Get a bow that has room to increase in poundage, as you can increase it as your muscles strengthen. I would recommend a release aid also. A taller bow is more forgiving, as is a deflexed riser. Risers (the center grip section of a bow) come in 3 forms--deflexed (like the letter "D"), straight (like the letter "I"), and reflexed (like a backwards letter "D"). I guarantee you will enjoy archery. They have 3-D shoots, where you shoot at various foam animal targets. And if you get into bowhunting, you will get a head start on all of the firearms hunters. Here in Indiana, archery season starts 6 weeks before firearms season and runs for 3 months! I hope all of this helps, and good luck!
