Hi Larry,
I hear ya on the cost, there is a small dealer here in my neck of the woods that sells Urals, Royal Enfields and Kymcos, but they also do alot of work on side cars. A couple weeks back we paid a visit to discuss a side car for my RSV.... man o man love the idea of a side car, but the extra 12,000 or so to get one on it is a bit daunting, checking some of the local adds here there are a few for sale but even the cost of those can be silly, I am in line with what Cowpuc said about a used Ural, that is another option we are looking at as well. The Ural is a very cool looking rig.
heck we have even found the doggles for the pooch so she can also go for rides.
Good luck with your search.
Mike
