Re: should I keep my Kurt?
yes they still are.
WRT the OP, I would keep the Kurt. There are plenty of times the Tormach 5" vise isn't big enough. Wish I had a Kurt D688 to work with again, and probably will buy one next time the planets align and they show up on sale at Enco with a 20% coupon.
EDIT: Enco has the D688 on sale now in their monthly hot deals category.... and there is a 15% off coupon!! Except.... the "sale" is $7 off. Guess I will keep waiting. A couple of years ago, the sale + 20% put it below $400. Lately every time they show up on sale, it is just like the current "sale".
