I like this era of Bundys and think that they can be a bargain. They do have a tenuous connection to the Conn "Chu Berry," but when the seller mentions that connection you can be assured that they also added another $300-500 to the asking price. My alto and tenor Geo Bundys are in better shape than the one you linked and I didn't pay over $250 for the tenor and I remember paying $140 for the alto. They both needed some work, but with new pads, etc., they can keep up with most anything out there. My alto Bundy is the horn that I've owned the longest. Others have come and gone. My Geo Bundy tenor died (and was therefore sold) under the crushing competition of an old Martin of the same vintage, but what tenor doesn't?
You should be able to get a clean Bundy "all in," i.e. ready to go with new pads, for $850. Others have commented favorably on the later Buescher made Bundy horns, but I've never had one. Regardless of who built the sax, my shopping goal is to find the cleanest, straightest horn, assume that it doesn't even play and will need $500 work. Assuming that it doesn't even play means I won't be disappointed. Also, although the accessories are often junk, check closely for a nice mouthpiece and updated (more protective) case. You will need both, so don't ignore the value of those items. A nice mouthpiece and case can also indicate that the sax was loved and cared for.
