I think next year I will order this desiccator:

I like the idea of refilling the Dri-Z-Air with the 13 ounces of new crystals each year (<$2.00).
I ordered the 8-ounce bags for this year (12 bags). But, I learned in the process only silica gel type bags are re-usable by the microwave drying methode mentioned by MNBoxster.
The bags I purchased are clay based, and not re-usable, since the bag material only allows moisture in, and not "out" by heating in the microwave. FYI.
