When I got my 8 gig III's, they were available on a black Friday deal from
Adorama for $69.95 each, so I ordered three. They were $109 normally as I recall. Then, I went out to Fry's to give my credit card a walk and let it take a leak, and Bammo! super, in-store Blow Out price of $49...this was in late 2008 as I recall...maybe it was 2009...those two years kind of blend together for me.
One thing I learned years ago was not to ever spend "too much money" on cutting-edge CF cards that were either ultra-large for their era, or ultra-high performance for their era...back then, 8 gig cards were really quite rare, and the 30 MB/second SanDisk's were the absolutel fastest cards on the market--and, this is the critical part--I bought them specifically because of Rob Galbraith's CF Card Database performance figures because they were to be used with a Fuji S5 Pro camera....a camera that writes 25 Megabyte files, and has a rather small buffer and rather slowish write-to-card times. The S5 Pro was/is one of the absolute worst cameras in terms of write to card speeds, and a test I found showed that with the San Disk 30 MB/second cards, the camera was over twice as fast at clearing the buffer as with some other cards...
Even though the cards were priced fantastically, I had other, smaller Ultra II's and III's in 2-gig size...I knew that if I waited a year or two, memory prices would be lower, and capacities would be higher. In 2001, I payed $400 for a 1-gig IBM Microdrive, which was a negotiated price, down from $499 sticker...today I can go to Rite-Aid and buy a faster, 1 gig CF for $12.99...
