Best substitute for Mirin?

Thanks, guys! I might just have to make a special trip to the asian supermarket for the Mirin after all, wouldn't hurt to have a bottle handy! Plus then I won't have Sake in the house tempting me. ;)

Sake plus a little sugar.

Got this from the Seattle Times:

If you don't have mirin, there are many common suggestions for substitutions. You can just use dry sherry or sweet marsala, for instance. Or you can dissolve a small amount of sugar in a little white wine or sherry, perhaps a 1/4 teaspoon of sugar to 1/4 cup wine wine.
