Oops sorry dodger, went to sleep! I'm into tactical woodsball & scenario mainly so I'm looking at something like an A5 or Sierra one to start off with.
They're supposedly easy to maintain & keep in how working order.
I get the impression that the a5 in particular is a great starter marker (not a gun, I must remember that!) I'm told that it's a good marker to learn how they work, how to maintain etc before moving on to more complex bits of kit.
There are also lots of cool mods for it which is nice
