Ive shot egos since they came out, then got a a1 fly, never had a gat so soft on paint,dont need half as much fiddling around/setting up as an ego does, buy one from lips it makes sence, and if you get a free rotor then its a bit of a no brainer...New or used?
If its new i would go A1 Fly from Lips and get a free Dye rotor.
Thus saving me the equivalent of £300+ (£200 through not buying the more expensive Ego and £119 through not buying a dye rotor at full price)
But then again its all personal preference.
