Shoptemp had a little trouble with Kingston in the past, but they resolved that and there hasn't been a single complaint with their stock since.
I'd suggest the Kingston over the Sandisk, when Kingston's are good, they're better.
Actually, if you were going to buy just a microSD, I wouldn't buy from Shoptemp in this case.
Try and find a good canadian retailer online and see if they have some better microSD cards, ones like A-Data and Transcend are pretty popular.
I have a Samsung Plus and it's great.
