I have the Classic Army and I love it. Running it off an 8.4v 1600mah battery, 2 will last half a day of straight shooting. Upgrades and extras aren't too hard to find, about the same availability as with TM parts.
"Hey I'm the first one to say its a great country but its a straaaaange culture. This is a place where gun store owners are given a list of stolen credit cards but not a list of CRIMINALS and MANIACS. And now they're thinking of banning toy guns...AND THEY'RE GONNA KEEP THE F**KING REAL ONES!"
