You can still find these NEF/H&R revolvers for under $200, but they're going to be the .32 and .38 S&W calibers. The fact is with .22 the ammo is so cheap and easy to get that any gun chambered for it has a higher value; it's similar to the 9mm and 40. Because 9mm is so cheap, any gun for it will sell for 100 bucks more than the same gun in .40 S&W.
I've talked to gun store employees that agree with me that .32 revolvers are better than .22 magnum, but they can't justify owning a .32 revolver when the ammo costs "a buck a shot." When you can get .22 for 30 bucks a brick now, the appeal of any .22 LR gun grows.
