I would never buy a used OD (with tranny) without seeing for myself how it performs or buying it fully expecting to ship it back to the UK for a rebuild (aka John Roseby). I've seen too many issues with used OD's (that turned out to be paper weights) to go through the time of installing it only to find out it needs to come out again.
To take full advantage of the OD, I'd swap the 4.22 pumpkin for a 3.89 and have Nisonger Instruments convert the speedo accordingly. The OD w/ 3.89 is fantastic on the highways.
I bought mine from this same source, but that's only because at the time, I didn't know any better, and it may have been the only source at the time. There is more than one guy on the planet that can rebuild these. I know there are two here in the states, (one very well known Sunbeam guy) you can get a complete rebuild done. It's very expensive to ship these overseas.
