I see what you are saying. It does seem as though there are alot of used DA's out there. The main thing is getting it from a reliable source. I have had too many bad experiences with used engines of different types to risk it. I spoke to Keith around the first of January and he told me he sold over 100 BME's in the last month. Maybe there will be some more out there. There are a few 110's on the used market though, but not as cheap as a used DA.
