RE: Should I go all out
I've got a 90$ mckenzie aim rite 3-d deer. IMO they all do the same thing. If the vitals are replaceable you'de be doing good to pick one up for $67.00.
Just think of what else you could spend the $100.00 on.
For the extra c note you may get a target that pulls arrows better. My aim rite can be tought to get the arrows out of but they will both do basically the same thing, Give you a life like target with vital area outlined.
