D6
I have a nice D6 for cheaper than your 150.00 bottom $. It is in decent shape and has a tiny bit of taper roll, nothing leaves the table except the shaft, and you can barely see light. The shaft is around 12.7-12.75mm and 3.8oz. The butt is stained purple BEM and is 15.2oz. There are a few dings and shows wear from normal play. Cue is solid. PM me if interested.
I also have a Jensen sneaky that I think has a 3/8 10 pin that I will let go for just over your bottom $. I will provide more pictures of which ever cue you would like to see if you give my your email address.
