Yes, Jim made a nice bow (I think if he did get back into it he would have a long customer waiting list in short order) and yes, they ARE getting hard to find regardless of the model.
I recently found a Stingray that has an odd label, at least compared to the brochure. Despite the brochure saying that Stingrays are longbows (i.e., not a flatbow) the lower limb says 'Stingray Flatbow'. Not sure if there was a change in how he built them or maybe it's just a mislabel, but it's an interesting 'quirk'. And it still shoots darn good!
