Warning! Buy a high quality memory card

I just had my generic memory card, Pro Max, crap out on me. I got it for free when I bought the Canon 40D and did not think about picking up another memory card because it was 4GB in size. Well I guess you get what you pay for, which in my case nothing because of the free memory card. I lost all my pictures I shot and was very pissed that it happened. Lesson learned. Remember to pay the extra money for a good quality brand memory card. I will be picking up a San Disk Ultra II Compact Flash 4GB card. Stay away from the generic Pro Max card Costco sells.
