I have had nothing but duds (some faster than others) on nearly all electronics that I bought on this site. I finally resolved this problem by not buying electronics here anymore. I`d would not touch such an expensive item with a 10 mile pole, especially knowing that MD presumably offers a 30 day warranty. You know this shit will break after 32 days. If you have a good CC with extended warranty that will cover this purchase and you like to live on the edge, I suppose go for it. I, however, rather avoid the frustration despite how tempting it might be. There is the option to buy from B&H video with the smallest SD card possible (in case you have or want to buy a different type of card). This could lower upfront cost especially if you have a card already.
