Just picked up an ER5 (had a gift certificate and a coupon code so got an even better deal!).
The site says these are refurbished and "B" condition, but - the one I received is essentially like new! No scratches, no smudges, clean and shiny and a brand new grip. Nice!

Looks like they have ER1, -2, -3, -5 and -7; the 5, at least, was available in three lengths and there was a LH.
