I sold mine in less than 24 hours on here, 750 and it was open.I looked in the classifieds here and see three for sale with Sure Grip chunks in them (Mine included in that three) and they don't seem to be getting much attention.
I know they are not cheap but I thought that Summer would be a great time to sell stuff since almost all the shows and swaps are in the Spring, Summer and early Fall.
What the heck ??
