How was I being a wise ass? I was simply making you a counter offer. Carbon fiber shafts are becoming more and more popular, with lots of brand choices. Cynergy is clearly the most popular as of now, at least in Colorado.
Becue is a brand a lot haven't heard of, and yours is specific to radial pin, 12mm shaft, used (not new in the box), and a tip most don't play with.
These add up to a product that is not in very high specific demand at all, so I think $300 is very fair. For $375, I would just spend the extra $75 to get a brand new one, with a tip that I'm not going to replace.
Good luck.
