what is the max microsd card made and that tp2 can handle

[doogie]

+1 on A-Data and also Transcend. Both manufacturers make good stuff that has consistently been flawless for me. I usually get 'em from Newegg.

Here's a Class 6, 16GB card for around $67, not bad. Fastest, highest capacity.

And an 8GB Class 6 for a pretty unbeatable $18. Good compromise here on speed/capacity/price.

8GB seems to be about the sweet spot. For the price I wouldn't settle for less than Class 6 speeds.
