If its not used, then yes, its a good deal. You can get a 32mb DDR Radeon for like $170, a 64mb for like $250.
Since it sounds like your on a budget, I would really recommend a GeForce2 MX. If you must have glide, you can pick up a Voodoo4 4500 for like $150, but they do not preform nearly as well as a GeForce MX.
The new cards around the corner will all be $300+ most likely. Remember that the Geforce2 GTS 32mb DDR was anywhere from $250 - $370 when it first came out depending on the brand.
I highly recommend the Radeon 32mb DDR for its value/performance. It looks purty too
