I've got a Marushin Raging Bull and it's very sexy. Got a nice cocking action and some nice brass shells to suit. Fires 8mm instead of the standard 6mm, and it quite accurate.
I haven't gamed it yet and don't really plan to. Since it depends on the shells for loading, it's not really the most practical firearm out there. And extra shells aren't cheap. I've seen a few sites selling them $30 for 6 shells.
I suggest you go with the TT-33. It's much more practical and effective in the world of airsoft.
