Incredible micro sd card recommendations

We bought an Incredible for our daughter, Margaret. The Incredible came with a 2gig card. I would like to get her a 15 or 30 gig card. Margaret will be in town next week and I'd like to have the phone ready to go.

So, my question is, what brand/type of card do you recommend. For my camera I usually buy cheap SD cards. Should I buy a better one for the phone?

Thanks
Monty
