I bought a new land pride BH1575 last week that had been on a dealers lot for at least 3 years. I know at least 3 years because that is how long ago I was told Land Pride quit making them. It has some rust issues, but has a new warranty. Final price was $4,000 cash, tax included. I would suggest looking to see if there might be a similer deal in your area. If I remember correctly, Great Plains made Land Pride, and they still advertise backhoes.
The backhoe that I have was a Bradco 408W that came off of Bobcat skid steer. The dealer took off the quick adapter and bolted on the 4 point mount and the fit is good. So there are more possible combinations to look at if you can find the right mounting kits.
