I've been using Sandisk, back in digicams, and the D70. I read somewhere that the D2X works better with Sandisk. Then I read somewhere else that the Lexar works better with the D2X. I've personally never had any trouble with Sandisk, using the Ultras, and now Extremes, but just the 1 gig versions. In the past I've used Transcend, but started buying Sandisk...and have been happy. So is one better than the other, in pratical real world usuage? Or does it make no difference? My D2X should be here next week.
