My guess is they were made around 2003 or 2004, don't know for how many years tho. Checking ebay completed auctions, they are selling for $175 to $255 on average, depending on how they are rigged. Hope it helps.
They came out in about 2001 and stuck around for several years. They are a dandy little speed bow. Fully rigged depends on what they have on them. The last one I had was about 2-3 years ago for my wife and I got it for $200 then.
