There is a spreadsheet of bucket mounting specs on another forum, I don't know if I am allowed to crosspost here. If you know the pin diameters, pin center spacing and mount width you can find a lot of good used buckets. Craigslist has them as does Ebay (but shop local as shipping is expensive). I found a used Geith 12 inch bucket for the excavator for $400. I had to drive 3 hours to pick it up but it was like new with almost no wear on the teeth, bottom or side cutters.
