If you are after an heirloom gun, buy the HW, probably the HW35E from Airguns Of Arizona. Beautifully made and a very nice walnut stock. There is absolutely nothing wrong with the Diana 48, especially seeing as how it is fully tuned. They even get respect from the owners of "more expensive" guns. Like the Corvette/Porsche comparison, would you sell a tricked out 'Vette so you could drive around in a Porsche? And, speaking purely from a personal perspective, I think I would rather inherit the Corvette over a car that's a good bit more common (at least around my parts).
