• SanDisk Extreme IV UDMA 4GB CompactFlash – $97.50 with $45.00 mail-in rebate
• SanDisk Extreme IV UDMA 8GB CompactFlash – $187.50 with $75.00 mail-in rebate
• SanDisk Extreme III 16GB CompactFlash – $164.95 with $90.00 mail-in rebate

The 16GB is looking like a great deal, if you are comfortable putting that many eggs in one basket, as the saying goes. I use two 8GB Extreme III CompactFlash cards and I also have a 2GB Extreme IV.
