Jon,
I would be interested in some of those MTx190 size 14 needles. Unfortunately I don't do eBay. No PayPal, and trying to find out if the seller will take other forms of payment is a pain in the butt.
I've got some size 12 MTx190s and they work OK, I want to try some 14s and 16s in it.
My only original needle got ..... busted. I have it taped on a piece of cardboard as a measurement item.
Joe
