I have a Sony TG3 coming shortly and have been checking out mem stick prices i've noticed places do this adapter where you can put 1 or 2 microSD cards in and it will act as a Pro Duo card, this seems too good to be true. Now i've read that the TG3 isn't great with normal Pro Duo cards and really needs the 'mark 2' cards to be reliable, is this true? also anybody have an idea of the transfer speeds with these adapter things? are they reliable? are they fast enough for HD cam footage?

any help appreciated
