Hey bherdm, there have been a ton of remakes made for SMW but your best bet to get the game is off of http://smwstuff.net/
by clicking the "Get Game" in the upper right hand side of the page. This is where you will find the 1.8 beta 2 version of the game, which I'd assume is the latest official release.
fluffypillow was making a netplay version awhile back (who also created the new site linked above), but it has been awhile since I've kept tabs on this. It may or may not be completed, but you could try and search for that version too if its available.
Hope this helps!
