Good price: I Purchased a new ANS GENX-2 front pneumatics kit for $80 on ebay shipped wo/ front block.
3(4) way has shorter travel: Allows for closer timing and/or slotless trigger plates.
Adjustable front Reg. : Increases efficiency just a little.
Stainless Ram : Well, whats not to like.
looks good : I got the pewter finish, it looks much better than sock.
Only one thing: the 3way could be better: the threads on mine are a little smaller than the threads on the stock 3 way. This allows the valve to travel left to right slightly, causing a small leak if I put any pressure on it.
I can pump out the paint a few bps faster than before.
If you can find one for under $90, and want an improvement over stock, pick one up.
