i personally got a mini as my first electronic paintball marker. love it upgraded the barrel to a knight stick and that's been all. never have had any problems and its a great gun for the money. i would suggest looking for the 3rd generation mini heard problems with air leaks with the first two generations
if you do have the money to spend on a axe and your a new player i would recommend that over a mini. there much easier to work on and having the feauter with the bolt the slids out with a twist and push of a button over the mini thats bolt is screwed in, makes it easy for cleaning at the feild if a ball brakes.
