I have a single drill 14lb cell for sale.  It has 50 games on it, cleaned after every set.  It has also been rejuvanated and resurfaced back to its factory condition.  This ball has a few nicks in it but its just from normal use.  I want $65 shipped for it.  I don't have the span measurements but I can get them.  Send me a pm and I will email some pics.
