Tippmann is really the best company for a beginner or mid-level player. I would personally suggest the 98 Custom, the Project Salvo, or the Carver One (the last two are in conjunction with U.S. Army paintball). All are good guns, based off of the original 98, and will work well for many years. For a beginner, I wouldn't suggest the A-5, because if you don't know how to take care of it parts like the cyclone feed may stop working. Also, Never get a gun at walmart, period, never buy a Spyder, and stay away from BT guns like the BT tactical (which looks similar to the 98, and is essentially a cheap rip-off of it)
