Go for it. A stock 2k3 or 2k4 cocker will be sufficient for rec-ball play and such. Most people will jump and tell you 30 different things to uprgrade. Try playing with it first and see what you don't like about it, and then upgrade what you don't like.
Cockers are reliable guns as long as you don't touch them. As soon as they work well just leave them how they should be, and they will work for along time.
