Yep, go shoot a lot of different bows from different companies. Martin makes some fine bows. Pearson/McPherson, Darton, Hoyt, Parker, Kodiak, just to name a few. There is definitely no reason to have to spend a big chunk of money to get something decent. You should be able to find some really good bows for $400 and less. Spending more often buys you nothing but advertising for the next fool.

Don't know how long your PSE is but I can remember when compounds first hit the scene. They measured 48" to 50" and some said that was too short to be stable. Funny how we were able to shoot these things from treestands. Well, now they're down around 30", and this is getting too short for best accuracy. I'm a short guy, 5'8", with a 27.5" draw and I still prefer bows in the 35" to 38" range. Why? Because they allow me to use shooting form that I am familar with (30 years of shooting compounds). And overall they are more accurate and forgiving in my hands. So don't let the ultra-short crowd give you the idea that short bows are the gods-end for treestand hunting. They have their own problems, too, like more severe string angle, more side torque caused by the cable guard, and more severe cam-lean if it's a single cam bow.

Whatever you decide, just make sure you get the drawlength right. Most people shoot a couple inches longer than they should and never achieve the accuracy potential they are capable of.
