Is it the Matt or Polished one?
Polished ones are somewhat rarer and harder to come by.
Either will sell well (if you bought to sell that is), but the polished one will sell quicker and easier and may command a slightly higher price.
The kick is still a nice tool to have, and is discontinued too, but the price could be around half that of the sideclip.
Good find. Seem to be getting harder to find now as most people who know what they are tend to hold on to them.
