Gosh id take the PM7 over a mech or any woodsball gun this side of the DAM, get a virtue board they drain the batteries less or just carry and extra battery? Is it really that hard to restric your self from shooting fast? cuz If you can you will still always have the firepower of the PM7 if you get over run, with a mech you wont.
Last make sure you use high quality batteries maybe even energizer lithium's just for the scenario games if you find they last longer like claimed.
The Invasion ($499), Drone ($429), Reflex Rail ($450), and Axe ($460) are all great markers. The problem is the limit was $400 and the original poster wants to buy new over used. Zaxion, if you can stretch up to one of these you'll be very happy. They are going to be more comparable to your Rapper than anything else I mention down below.
No guna quote all that lol
Any way I agree with everything except I wouldn't say the guns under $250 lack quality but features, in some ways the Extcy and PMR are better quality than $300 and up guns but they do lack features
And where are you getting your efficiency numbers and what size tank? A G3/4 which is like the worst efficient thing ever gets like 6 pods off of a 68/4500.
