Personally I would go with the Nvidia glasses, but I believe any generic DLP shutterglasses will work so you can save some money (like these:

Some games look better with one or the other but overall they are comparable. Yes, some DLP sets have issues with overscan, this is a hardware problem so it will be across the board whichever driver you use. If you want to do PS3/BluRay 3D then don't get the Nvidia glasses. Nvidia is PC only. The generic glasses should work with anything, though.
