My first bike after a riding hiatus like yours was also a Shadow 750, but I found a 1984. I still have it and just put a new saddle on it last year. Now I also ride a Honda ST 1100 for longer rides and also to commute with my wife, who loves to relax on the pillion.
Glad to have another Shadow rider among the ranks. Welcome aboard!
