I purchased a low end parker bushwacker for my son to use as a mentored youth. He shot a buck i shot a doe with it..(testing lol). For 300 bucks you get what you pay for. But it dropped my doe in her tracks with a shoulder shot and his 5pt went about 80 yards. At 20 and 30 i am extremely confident. 40 id be very hesitant.
My best advice is to shoot a few just like you would when selecting a new vertical bow. Look for the above mentiond features like the crank and safety. It has been my experience that if cables and the rail are properly lubed string life is not an issue. If i had to purchase on for myself id look for a reverse limb model or and Excalibur.
