I still use a 16 gb one for my DSLR. When I bought it about 7 years ago, I opted to get an older entry level canon which was basically better specced than the current (at the time) entry level model and far cheaper. The new model did have wifi though so I got one of these. Works pretty well. And other apps support them not only their included one (PhotoSync on iOS comes to mind). They are slow AF but get the job done.
