1 dollar, semi-auto spring pistol from the dollar store, bought several
Terrible little things but were fun for a prank, guessing under 100 fps with .12's..
bought 3 Krakens for 100 each, two of them are for other people (each adds about 30 bucks in taxes and shipping so 130x3=390)
ASR for 110 on sale, then with shipping, .43 bbs, border fees ect cost me around 180.
co2 pistol for about 80.
...sooo effectively I've managed to spend more than some of these people on their first real guns, but in the form of a small armory.
