i think the colt guns have peaked in price. seems the kool-aid guys already have the models they want/need. the rest of the people are happy with "lesser" models at almost half the price. plus when there is a BAN scare the sales go up with the collector guns.
the Swiss CQB guns seems to sell all the time. the full size guns sell easier if they are green or black. the smurf color seems to be very hard to get rid of. besides, most sellers are asking near or at the retail price, but of course less taxes.
supply and demand. seems overall there is a good supply of other toys.
