I wouldn't buy any backhoe if it has a unitized round-barrel single swing-cylinder. Parts are usually scarce and they are near impossible to fix once scored. They are also weak, as compared to dual conventional swing cylinders (or one big one with linkage). Deere used them in a few hoes, but pretty much all the AC hoes I've seen use them.
Maybe for a dirt-cheap machine - but $2600 is not dirt-cheap.
