something like this https://claz.org/classifieds?q=(2002...R+2005)+Rialta
Thanks for the search results. It's difficult to sort through all the listings, but i've been doing just that. Unfortunately, many of the ads are bogus (Rialtas for $3500??....and several of the legitimate ones are no longer available. And if I watch one more youtube video from a lot salesman pushing a Rialta in an ad that was posted in 2010, I'll be suspect of any ad that is more than 30 days old.
Nonetheless, I appreciate the link. Whatever frustrations I might be experiencing in my search is certainly not because of anything you did. The link WAS helpful.
It's a good thing I'm not in a hurry!
