here this is the best site for comparing gun prices cuase most of the time they are the lowes here. Or you can go to
Paintball Watch which is kinda like priceline. I would go for a cocker but if you want and electro go with an Impulse on the low end ($400 new) or a Matrix a little higher up for $670 new. The nice thing about the impulse is that you can run it off of Co2 just fine until you get a nitro tank. The nice thing about the Matrix is, well its a damn fine gun, plus it comes with a CP barrel stock so you wont need to upgrade that.
Oh yeah, I am across the pond from you picaxe so all the prices are American $ and the shipping will probably be pretty high if they'll ship it all the way, but $670 for a new Matrix is pretty ncie considering the exchange rate you guys enjoy.
