WTB: Micro SD Card's 32gb+/64gb+ prefered

[Ryankirsch13]

Title basically states it. Got my girlfriend a micro sdxc and her phone doesn't always agree with it. Sometimes it reads sometimes it won't. So I'd like to go basic with a run of the mill SDHC. Looking for larger capacity though.
Currently using a 16gb aND a 32gb, I'd be interested in 64gb+ but maybe one 32gb. Shoot me an offer! Thanks.
