Kingston CF Card
I have used this card in my Canon SLR 40D and it works fast. You can pay a lot more for a CF card but this Kingston card works great at a lesser price.

Very Good Value
I have some Extreme IV cards that I like but wanted to have extra CF cards for the times I did not have the ability to download my shots or if the worse case scenario happened and a card went bad.

I purchased a couple of these cards since the price was right and they were available in a good size (4 Gigs)

These cards have been reliable and performed well if not quite to the same level as the SanDisk in terms of burst shooting from what I could tell. For most shooting this is probably not going to be an issue. For parties, family get togethers and similar things these are fine.

It is more situations where you want to get every possible shot in high speed shooting modes with RAW that it could be an issue.

If you do not really see yourself worrying about the high speed modes often (and even then a slight performance increase) then these are a good buy.

Excellent card, great low price.
Bought this card as an alternative to a Sandisk UltraII for a few dollars less. Have been using it for a few weeks in my Sony alpha dslr with great results.
This card is very fast. I was able to capture a fireworks show with continuous shooting and my my fps were only limited by my camera's buffer, not the card's speed.
Only con is that it holds about 100 shots less than a Sandisk 4Gb.
I would highly recommend to anyone looking for a 4Gb CF card for less than a comparable Sandisk.
