What titan said.
I shot a bunch and bought a PSE a few years back. I got a DreamSeason EVO. I believe it is the best hunting bow ever made. I've shot nearly every top of the line bow kn the market since and none shoot as good as mine. This is all my opinion on what fits me.
I would NEVER buy a used bow unless it was from someone that I knew well. Ive seen too many people buy a bow and it has a cracked limb or other issues. That "cheap" used bow just cost them more than a new one.
If you are wanting to keep costs low, look into package deals at your local pro shop. Stay away from the big box stores and their so called "pro shop". Most of those guys cant cut arrows properly much less set up a bow for you.
Hmmm.. the MQ1 that I gave $200 for at the pawn shop still slings a 400grn arrow at 285, and kills deer just as well as it would if I had bought it new. Just be sure to check it out well.
