Hi, I purchased a SDHC 4GB card a while back and just opened the package, didn't realize what I bought and the card won't read on my pc. I wanted to get a reader for it since I can't take it back as it's been several months ago. Has anyone every bought those little $2 usb sdhc readers off of ebay? If so, is there anything i should know about them before I buy one? Too good to be true? are most of them faulty? is there additional software or drivers I'd have to download or buy? Do they read very slow? Do they last more than a few reads? Just curious. Thanks!
