Yeah, I'm on that forum under the same user name. As to that 18hpish diesel you'll find plenty of them on those get-it-from-china-now sites. They cost around $800 ($750-$850) FOB some Chinese port. Some of them seem to offer single engine shipping, others start at 5 so a co-op buy might be in order if you can get more prospective dieselers. As to the quality of the respective 'brands' I don't have information yet but hopefully a new thread to be started on the
dieselbike forum will enlighten us all.
