Well, for under $50 I'd prolly get a TnT2 M64... They can be had around $30 if you search. Other options are cards with the Savage4 chip, but since it is no longer supported I'd rather have a TnT.
For $60 you can get a regular TnT2 or a Voodoo3 2000. Well worth the extra cash, IMO.
If you don't play alot of games, or are willing to play games at 640x480 get the $30 TnT2 M64. If you want to treat yourself get a regular TnT2 or a Voodoo3.
