There is almost no demand for them. It may be worth a few more bucks because of the caliber but the 742 was a big no no by Remington. Many shops won't even work on them anymore. A lot of it is because Remington won't make parts for them.
I used one for a few years and shot my first two deer with one, but even then it was a single shot. But, it's all I had so I used it.
