For a new player, its EXTREMELY tough to beat anything Tippman.
The two favorite MARKERS that I've owned have been an Angel LCD and an '03 STO 'Cocker. Both markers shot more then 100 cases of paint through them combined with only 2 breaks. They always worked. The cocker was a touch more accurate, but I honestly believe that it was because of the barrel on it (14" CustomProducts).
Take my words with a grain of salt, as its been 4 years since Ive played/ been in the scene. However, if I were to buy another marker, I'd not think twice about anything WGP or WDP.
