Probably worth more to you as a spare gun to be honest. I've got one nearly the same and have just dropped a virtue board in which i happened to have lying around, changed the marker and is very cheap balling to be honest.
Cheers for the advice guys! I appreciate it.
I'm still in 2 minds whether to keep it or not. I've already got 2 backups so I don't really need a third, we'll see. Might be up for sale by the weekend
