Best starter marker that uses Autococker barrel

[James]

I have an autococker with a total freak system and would like to buy a second marker that I could share the barrel system with. I have heard the GT-2000 is a good marker and that is uses the a/c barrels. What do you guys think?

W/ the freak its not that big of deal which marker..you can just purchase a new back for fairly cheap.. Might be the best option if you cant find a marker you like.
