I have an old M3 DS Simply so Im out of luck (and forgive me if no one can use 8gig cards at all but I know some support SDHC) but:
Clubit.com has the A-Data 8gb Class 6 SDHC Card for $28.49 + $5 for ground shipping. Most deals I saw were right around $30 after rebates so I thought this was a good deal. I have quite a few A-Data cards that have performed pretty well.
