Koyker makes a great deal of loaders. They seem to be stout and priced reasonably. You can get more lift capacity from them than the factory loader.
You can also check out bush hog loaders and woods loaders. But, of those, the Koyker is probably going to be the cheapest. Wallenstein (I think that is spelled right) also makes loaders and may have one for your tractor. One of their reps posts here at times, you should be able to search for them. They may be a sponsor too.
