There are all kind's of bow's out there that you probably would like and could pick up in the same price range including a few accessories .BowTech [If you couldn't tell is my favourite] but might not suit yourself,but then again it might,Mathew's is a top line bow ,Hoyt ,P.S.E make's a good bow ,the list can go on and on .I reccommend you find a repitable shop in your area and see what they sell .I can tell you which bow's are top of the line but I can't tell you which bow is for you because what feel's right for me might not be right for you it's all a matter of feel .
.I understand how you feel about buying the best up front ,I'm very much like this myself except when I was unsure whether I was going to like the sport or not. That's how I felt when I bought my first bow .I bought a 1 yr old Golden Eagle Splitfire, and shot it for 3 year's but knowing that I knew now,just how much I liked this sport .That's when I had decided to go all out and buy a top line bow .
Some bow manufacturers might have different mods for draw length's that you can purchase and are a quick fix,Some have enough adjustment that all you have to do is move the draw stop's.and if the draw length is 1/2 the I would just add or subtract a twist in your string which ever he needs shorter or longer [Just a temporary fix].
But definetly DO NOT buy a high end bow without test driving it ,you may be sorry if you do.
Hopefully I've helped
