That picture brings back memories of literally dozens of those guns - NIB - sitting on local thrift store shelves back around the year 2000.
American Laser Games, you see, was actually founded and headquartered here in Albuquerque. Around the time they folded up and sold out, all of their excess inventory was dumped off at Thrift Town - Lots of those guns and more Mad Dog McCree CD's for PC and Genesis than you could shake a six-shooter at.
I should have grabbed a few when I had a chance. But hindsight is 20/20, and I was neither much of a Genny fan back then, nor did I really realize or appreciate Albuquerque's particular contribution to the videogame industry at the time.
As for the current rarity - I couldn't say, but I bet I could dig up a few loose ones on the cheap ($5 - $10) at the local shops.
