I was wondering if there was a difference in the quality of the photos depending on the brand of cf card? I'm finding they are generally the same price, so does it make a difference?
I have never seen anyone suggest that the equality of the images you capture depends on the "brand" of CF card you use, but then I have never used anything other than SanDisk. I think you will find that the Image Quality (IQ) depends more on the lens you are using and the "skills" of the photographer - getting things in focus, DOF, etc.
Where the difference may come is in the actual quality of the card itself - how long will it last, is the particular type/brand prone to "failures", etc. There was a posting here a while back about a photographer who had shot over 700 images at a wedding on a 4 GB Lexar SDHC card and when he went to pull the images off the card, there were problems - the card seemed to be corrupted - not sure how he got over 700 images on a 4GB SDHC card...
The only suggestion I would give you is to buy well-known name brand cards, e.g. SanDisk, Lexar, Kingston, etc., and to stay away from any "house" brands you may be offered. Of course, you should always have a spare or two, just in case one of them gets compromised, or you fill up the one in the camera. As well, shop around, prices can vary considerably and check on some of the on-line sites as well, e.g., The Camera Store, Henry's, Vistek, Black's, etc. HTH.
