I own a Etek 3 it is a nice solid gun! super easy to maintain! I would recommend if you get one that you get a barrel because the ball drops pretty hard with the stock one. Also the gun is pretty loud, but I love it ! Also I have the LT and it is pretty much an identical feel to the AM which my friend owns so I kind of think he wasted the extra $100!
They actually just upgraded to vibes as there rental gun I think. The other upside of this is they have an outdoor field and a proshop about 2 blocks away from the indoor field. BUT the indoor field was the best =[.
