Dan,
I never was looking for a loader until a buddy came over to my place with his Johnson. I was hooked and now don't know how I ever collected cubs without one
! There are Johnsons, Dancos, and Kwikways. Some guys have nice homebuilt models, too. Kwikway still makes em brand new and IIRC, they are around the $3000 range?? The Dancos, older Kwikways, and Johnsons range from $500-$1200 range depending on what they look like, model, if they work, and location. This is usually for just the loader. Ya might find a good deal and get one for the lower range or less.
Update on my loader. It's one the 129 and works like a dream. I plan to snap some pics today and will get em posted. Need to get some weight on the rear, though.
