mountain man...was just wondering what your planned use for the gun was since you specified it was going to be a snubbie...
J's run from 2" to 6" and the price is just going to be determined by the rarity of the Model selected.
If you want a fixed sight the new ones mentioned above are all excellent. For one with an adjustable sight you would be looking for a 2" 34 (blue or nickel no longer made), 63 (very expensive), 651 (very very expensive .22 Magnum) or the 651 that has the extra .22 Long Rifle cylinder (incredibly expensive).
Ammo wise .22 Magnum is more expensive but will have a 200-400 fps gain over .22 Long Rifle depending on the load and barrel length. From a 4" barrel some of the .22 Magnum loads will run 1400 fps. Most Long Rifle ammo will run 1000 again depending on the load.
At this point I own a 3" 317 AirLite, 3.5" 51 with an extra Long Rifle cylinder, 63 4" with an extra Magnum cylinder and a 6" 35 that has also been fitted with a Magnum cylinder. I've owned several of the 2" guns, 34, 63 and 651 but sold them all off.
Probably my favorite J-.22, a Model 63 with extra 651 cylinder...
Dual cylinder 35 6"...
51 3" .22 Magnum that has an extra LR cylinder...
...you won't stop at just one....
