DDR2-800 is very affordable right now. I see 2GB kits as low as $40. That was not the case even a few months ago. OTOH, DDR2-667 is hitting new lows for any type of RAM. I've seen it selling as low as $18/GB.
Trying to go faster that DDR2-800 is definitely not worth it. It is often just overclocked slower RAM. Most enthusiasts will want to get slower, cheaper RAM and overclock it themselves.
