I've heard quite a few good things about them.
Dan Wesson made an excellent revolver; was used primarly for competitive target shooting because of it's amazing accuracy; the only major criticism of the revolver is it takes both hands to open the cylinder (the mechanism is in front of the cylinder and is pushed down, as opposed to being behind and pushed forward); unless you're in a gun battle, that makes no difference.
Dan Wesson went out of business some time ago; it has been acquired and reaquired several times but never came back with any resolve; the best I can determine, the Dan Wesson rights are now held by:

That seems unlikely, but possible; they haven't made this gun in many years so it's hard to believe it's been around for that long and never fired; but possible.
$250
Good price
I've also heard you can fire a .38 through the .357?
Yes; and for messing around, that's the way to go; I keep my loaded with .357 hallows at home but for shooting I use mostly .38's but always need to let go several rounds of .357's (otherwise may as well own a .38).
NOTE: Just for fun, when you're shooting with someone who can handle a gun, load up 5 .38's and 1 .357; be sure to have the .357 in the last chamber; let the person fire the gun and they'll think it's a bee-bee gun (firing the .38's) then they get to the last round - BAM!RECOIL; I love that

S&W .44 mag
"The most powerful handgun ever made" ; "Do ya feel lucky punk; well do ya!" - Dirty Harry; mid 70's (was just on the other day). BTW, .44 mag is no longer the most powerfull handgun.
Beretta 9mm, another 9mm
I'd be interested to know how much for those and what size they are.
