The only ones I've seen are the rectangular trays with a "shove" bar, but those are pretty slow since you have to align everything first. I think it's faster to just use your hands.
I have one of the tray types made by GUIETTE MFG. which has interchangeable trays for different types of links. It works great and will last a lifetime. It's much better than doing them by hand if you plan on doing several hundred at a time. YMMV TheMULE
