[Braillenote] SD cards for the mPower

[Shannon A. Reece]

Hello.  I am looking into buying an SD card, hopefully a 1 gig, for my
VoiceNote mPower.  There appear to be several various SD cards, which run at
different speeds.  I saw a 40x one for example.  The faster ones seem to be
pricier.  Which SD card is recommended for the mPower?  And what storage
amount is the maximum it will handle?
Thanks much!
Shannon
