I was planning on spending $350 on 1gb pc4000 corsair pro (512x2) but car problems came up so now I'm just looking for some budget ram to last me a few months till I can get the money saved up. These look like a good deal:

PMI Turbo Memory 512MB DDR 400MHz PC3200 Dual Channel (2x256MB) Gold CL 2-3-2-6
Price: $114.99

PMI Turbo Memory 512MB DDR 400MHz PC3200 Dual Channel (2x256MB) Gold CL 2-3-3-6
Price: $99.99

PMI Turbo Memory 512MB DDR 400MHz PC3200 Dual Channel (2x256MB) Gold CL 2.5-3-3-7
Price: $94.99

PMI Turbo Memory 512MB DDR 466MHz PC3700 Dual Channel (2x256MB) Platinum CL 3-4-4-8
Price: $136.99

Which one of these would you guys suggest?
Or is there other ram near $100 that is better?
My system:
P4 2.6C 800mhz
Abit IC7 motherboard

anybody?
