Could you be a bit more specific?
They have started carrying "Dongwa" branded feeds, which I know nothing about.
Or possibly the "flat" design to fit the popular dovetail mills? While I dont have that flat design, I do have 3 of their PF's in the "Align" brand (or sometime with a Shars sticker) for my Bridgeport clones 3 axes. The Align brand has a good reputation and there are parts available.
