I completely disagree with Alien. The New Timmies: GZ, 2002, Dragon all run at 85 PSI! Once broken in, they shoot about 1500 balls on one 68 45 tank. By the way, I'm curious as to why you would want a dragon. On a performance point of view, they work the same as the new 2002 models, only their asthetic value ans a slightly lighter weight for the Dragon distinguish them and to pay about $500 more for just that is absurd. Timmys are prob the best all around gun on the market because of their speed, accuracy, and efficiency. Good Luck finding a well priced Dragon, here in the states they are about $1300 so next time you come play in a US tournament, or vacation, pick up one on the way. It'll save you about $300 from getting it in the UK, and they're relatively common here.
