i know your probably not going to like this, but why dont you go with a more efficient marker. spyder mr-2 w/ eyes is $250 new, then you can upgrade it...this is just a suggestion, not an order, so take it however you want...

as for the mr-2,
1. its an electronic stock w/ single-shot, burst, and full-auto fire
2. has eyes so it wont chop(though they can be turned off)
3. has plenty of upgrades
4. is cheaper than the overpriced(dont kill the messanger) tippmans
