my thoughts, based mostly on tractor house and other web stuff i found was similar to yours. Was thinking of trading it on a used 4066r and the dealer came back with 13.5 which seemed really low, given the hours and replacement costs these days.
After all if one of the advantages of the big 2 or 3 is residual value why am i not seeing it?
another route i could go is a used Yanmar YT359C for like 12k less with 200 hours less- the risk there is parts and dealer- i am confident that the quality of the Yanmar is at least as high
