Phil, You are very right about the Ural in my opinion ,although they have came a long ways in the last 10 years.
The older wings & HD's can be found already set upon occasions for reasonable prices , also older BMW's , just a matter of being ready to jump when one comes along!
I am aware of a local HD guy that found a like new HD sidecar that was like new, he had it shipped out of CA into the dealer of his choice to have it mounted and the reverse gear put in his existing Road King. I think it cost him arround12,000 by the time he was done as he already had the older Road king. they are a all HD family another RK with side car, and the wife is on a 93 Soft tail springer!, LOL they are both olde than I am!
old him I sure was glad it was him that found that new car and not me and he just smiled at me!
