BUffalo 3700 replacement?

Well I really screwed the pooch on this one. While building my system I only bought 1 512 stick on Buffalo 3700 memory because of budget issues. Well now that I am ready to buy the second stick the chips have fallen off the face of the earth.

I have a p4 2.4c CPU running on a ASUS p4p800 motherboard. I would like to get 1 gig of memory (2x512) to turn on Duel Channel but now I have no clue what to look at. My goal is to OC the 2.4 to like 3.2. Can anyone recommend some other bh-5 chips that should be a pretty safe bet for my overclocking goals but will not totally break my bank?

Thanks!

Heh, sounds like me, I did the same thing and still only have one. I just bought Mushkin 3500 to replace mine so I would of course say go with that.
