You could probably find a used Ti4200 or 8500 in that price range, but they're tough to come by new these days (which is why the prices are kinda high). There's also the GeForce3, but again, they're pretty rare unless you're looking for used cards.
If you really want to scrimp, and don't want to buy used, go for a GeForce2MX or GeForce4MX (AKA the GeForce4 "4000"). Last I checked they were still fairly plentiful. There's also the RADEON 7500, if you can still get those new...
