Hey guys Im looking at changing my CO2 powered VL Maxis RG, to HPA system. A) is that a good investment and B) should the Pure Energy 3000psi 0.8L System - http://www.gizmos-uk.com/Pure Energy 3000psi 0.8L System.html - work well enough with it at the moment? Also depending on the replies I get I may put a request for one up on the forum or is it better to buy it NEW?
