Just an FYI, I got bucket and dipperstick forces for the BK215 from Titan. (They sent me the manual) Bucket force 2592lbs, dipperstick force 1975lbs. Lowest of the hoes I have data on. (Titan, are you listening? The BH looks structurally sound, get the supplier to use slightly larger cylinders and get these numbers up!)
I have a spreadsheet of backhoe choices, and the BK215 is actually a couple hundred pounds lower for both forces than the FHM backhoe, commonly available on Ebay. I suppose the dipperstick numbers don't vary by a whole lot, but bucket forces range quite a bit.

Also worth noting that the Branson backhoe is made by Ansung, and very likely just painted different. Branson must be using slightly more pressure to it, or measuring differently. I included it because that's the hoe I could get locally...
It appears to me that bang for the buck,
Woodmaxx is probably a good choice. Their price does include the pump and tank, so if they come out with a version that runs off the tractor, it should be cheaper...
