Well first off if you want to use a rope cocker which is the most used type I think then you have to either read up on them or tell us how tall you are the length of the draw and where you have the most leverage enters into it, if you are 6'2" or taller and well musceled you can handle any of them. I am 6' and 70 yearswith a bad shoulder and I can handle a 200# Exocet. If you need or want a crank type the 10 point is best I have had one of those for about 15 years. As far as brand goes I have had several different ones and would recomend either a Excaliber or a 10 point and since the Excaliber is in your price range I will includ a link where you can price them they are very simple very reliable and very low maimtaince.
