I own the 16GB San Disk Micro SDHC card and am thrilled with it! Great for carrying around as much data as you can cram on it. One tip - order a San Disk Mobile Mate reader with it - it costs about $5-7 and is USB equipped. It's a really fast way to download all your files onto the card and just pop it in the Bold.
I found that Amazon had the cheapest price for the $16GB card - about $65+ I think, plus S&H.
