the old Dan Wessons were very good indeed, as were the old Colts
neither is all that easily found, nor cheap
your best bet is the S&W k-22, k-17, k-18, 6" barrels preferred, cost in the $500-$600 range (and up for the oldest models in really great condition re: "collector status" pricing)
in currently manufactured models, that translates into the S&W 617
the newly manufactured S&W so called "classic" line, I dunno, never shot one
but suspect they are not quite up to the performance quality of k-17s, for example
in SA only revolvers, there are the very excellent Freedom Arms models, pretty stiff pricing
if you own your own island nation, money unlimited, there is always Korth, of course
$500-$600 is pretty much the name of the game for a high quality 22 rimfire revolver, patience req'd to hunt up a good older model
if not that patient, try to find a S&W 617 somebody will let you try before you buy
PS
for me, k-17 rimfires and k-48 WMR woobies
lots to love about 'em
(the Rugers are good fun guns, but just not in the same class as the old Dan Wessons, old Colts, FAs, and S&W Ks)
