I say WAIT!
Not long, but a new motherboard revision (codenamed Jasper) is set to phase out the current "Falcon" boards. The new board will have a 65nm GPU instead of the current 90nm GPU. Although the Falcon board reduced the chances of RRoD greatly, it still has the same problem-causing chip that is found in the launch systems. The new GPU chip will use less energy and, more importantly, produce less heat, reducing the stress on the solder connections and preventing the RRoD. I'm currently using a malfunctioning launch system given to me with RRoD. I have fixed it numerous times and for the most part it works, but it needs fixed a lot. I'm holding out until the Jasper boards are in stores to buy a new system.
