I would agree it is worth a refurbish- BUT- first I would make sure that the inner connections on that cue are not loose- because if the cue has a buzz- we are talking about a lot more money than it might be worth to fix it. The cheapest , fastest ways to determine this for this cue would be : 1. screw one shaft on real tight and hold the butt end in the wrap area with one hand and open hand strike the lower third of the shaft with the other hand so that the shaft vibrates back and forth- LISTEN REAL CLOSe for any BUZZ coming from the forearm area of the cue above the wrap. 2. Since there are no tips, cheaply you can buy a slip on tip for about $1 and just slip it over the ferrule as tight as possible and go hit a few balls- see if you can sense any noise coming from that forearm area above the wrap area. NOT a perfect test, but better to do some of this testing rather than spend several hundred and then find out it is messed up INSIDE the cue!
I am only telling you this from years of experience collecting cues; where early on one time I did NOT test the cue prior to a refinish and could not recover MY investment because the cue had a messed up connection inside and I discovered this only when I started playing with it after adding tips and a refinish- do not count on Refinishing people to check out your cue for this problem- mine, a beautiful older Palmer; went to a well known guy years ago and he did the work without checking out the internal cue connections- NOT his fault or responsibility unless you ask first and I did NOT> Good Luck- Nice Cue!
