Prices for 16GB SDHC flash memory cards has declined recently. Class 6 16GB SDHC cards made by second-tier manufacturers like Transcend, A-Data, Patriot and PQI now routinely cost less than $70.
Here's a good deal available through 6/30: Zipzoomfly is selling the Patriot 16GB SDHC for $55. Shipping is $7, so a total of $62. After a $10 mail in rebate, your cost is $52. (I remember when a 1GB card cost more than $100!)
