Hmm, currently G-Force cards cost still a lot - there should be a GForce II or so out soon, then you can expect a price drop.
If you don't want to wait until then get the cheapest card with a TNT2 Ultra chip. Avoid any card wih a TNT2 M64 or any non-ultra TNT2.
Of course, if money is no issue then you can wait for the GForce II and spend it on that card
