I used to be a Crossbow user regularly, but it was when the Barnett Commando self cocking era was around. I know things have changed and I'm asking for input from actual users as to what to expect from the new models on the market. I'd like info on self cocking, strap cocking, lever cocking, is 150lbs enough?. I'd also like to know about the ability for scope additions, laser sighting where applicable?, most bang for the buck. I appreciate any and all answers, I'm going to use it for target practice regularly and want to know where manufacturer failures happen as well, such as poor implementation of features. Barnett?, Excalibur? Budget of 500.00 max Thanks in advance.
