I own them all! Actually, the demand for H&Rs, especially the Sportsman series of all eras - has dramatically increased over the past 2 years or so. Prices have doubled for many of the common models and the Sportsman pieces are selling, in come cases, at unheard of prices. You just have to be patient and hunt them down. Check the two main on-line auction sites: www.auctionarms.com
and the other forbidden zone site that sounds like gun combined with broker.com. There's always lots of them offered for sale on those two sites. Good hunting.
