If you're looking to buy a SIS440 card, I'd highly recommend you look at other alternatives from nVidia or ATI.
Is $60 your limit or could you go to $80 possibly? In that area you could get a GeForce 3 ti200 or GeForce 4 ti4200... see this thread :

I just haven't heard great things about the SIS video cards and their capabilities...
