Which is the best memory??

Right now I have an Athlon XP2500 rig and I need some new ram to get past 200mhz (currently have PC2700). I am going to upgrade to a A64 late in the summer, and I want to be able to use the same memory, and overclock to 220-240mhz. I wanted to go ahead and get it now, because I think the prices of these kinds of ram will go up maybe. Which one is the best, all of them are 512MB, Thanks!!

Geil! Golden Dragon Dual Channel... PC4200

I would go with the OCZEB series. It will reach the speeds you want 1:1 and give tight timings

Unless you want to wait for the new 2,2,2 series stuff coming out from Corsair and OCZ I would go with the EB. Possibly the EB over the newer sticks since we have seen some pretty amazing speeds from them at the lower vdimm voltages that the A64 needs.
