The best thing to do is read up on how to operate and maintian a cocker LONG before you buy one. When your cocker arrives at your door (or you pick it up from your local proshop) you should be able to maintain it and use with relative ease.
As for me, I'm just like those other guys. i have something for 10 minutes and it's in pieces. When i bought my first angel, first thing I did was install a new trigger, do the trigger job, and proceed to take it apart until there were no parts left in the body. I put it back together, used it the next day, and I've never had a problem with it. If you're not mechanically inclined or you don't want to learn, the cocker isn't the marker for you. Inevitably, every cocker will eventually need timing, new parts, or tinkering in it's lifetime. When the time comes that you want to upgrade it, or it craps out and needs fixin' you should be able to do it yourself, otherwise you'll always be dependant on others to fix your s%!t for you (which can not only cost you a fortune, but also be a major paint in the a$$). Know your marker. If you're not mechanically inclined enough to own a cocker DON'T. The cocker is NOT a low maintenence marker, if you want low maintenence and high ROF, the Bushy is a good choice. Know and love your marker, and it will know and love you back.
