I almost bid on two complete sets,(gun, target, holster and chest straps for the target), of these on ebay a week or two ago because the starting bid was 10.50. I've seen some of these auctions for for up to a hundred bucks easily...and this one didn't...I believe it didn't go over $15 :facepalm.
My buddy had two sets when we were kids and they were everything from han solo blasters(even though he had one of the hasbro ones haha), stormtrooper blasters, to our own advanced war/weapon McGuffins that we would save the day with...ahh memories.
