I just purchased one of these on eBay. I got several of the cheap SD card readers for .30 cents and etc. and they have worked flawlessly with SDHC cards. I have one 16gb name brand card that I use in my Nikon D90 but I don't want to mix it between the camera and the F-Series.
Other than that I have some spare 2GB cards. I am going to try it since I already bought one but would like to know if anyone else has used one and what your experience has been.
Thanks
