"Waiting" is the big key. If you are OK with waiting for a bit, you might wait a bit to see how Palomino and Northwood (Intel's 0.13 micron shrink) perform. Northwood would mean that the P4 will be cheaper and run cooler - however, requires 478 pin mobos.
At this time, I would really recommend waiting for a month or two & see how things go .
