In my opinion, it is the absolute BEST rendition of Street Fighter that money can buy. The dedicated has the cpo art in the blue cab. The board alone sells for insane cash, so I'd put a solid price on a SSF2T at around $500-$700 if in real nice shape.
The game was the last released which followed the standard style of the original. After that, the series branched off to the alphas, then sequels, etc. IMO, it never was any better than this one. While all the traditional controls and graphic elements are essentially the same, they were all improved upon. Updated character graphics, four more fighters, and added moves for some characters (which helped even the playing field between some fighters) all made this the best of the best.
