The best way to get a simmering alcohol stove is to make a second stove with fewer holes, or make an adjustable wick stove.

I have a wick stove from MiniBull Designs that works just fine. Also made a simmer cat.

Then there is this set: http://www.outdoorequipmentsupplier.com/products-stoves.html

I have one of these - they don't seem to be in production anymore tho. Tinny is too busy playing with remote fuel alcohol stoves.... You can get a half hour burn with about an ounce of fuel with it.
