I have an Eraser, 15#, first drill, in very good shape.  Has been resurfaced once and still has lots of pop.  I also have an Erase-it 15#, not yet resurfaced and the fingers were plugged for span adjustment but still on first drill.  The Eraser is in better condition, but neither is too bad.  I have hardly used these balls at all this year since our center seems content to put out an early hooking shot and these balls definitely need some oil.  I only bowl once a week (3 games) the last few years so neither ball has a whole lot of games.  $50 shipped is good for the Eraser and $45 shipped for the Erase-it.
