Steve,
Thee are probably lots of options, depending on the supplier.
I bought a 'mile' of asbestos wick material many years ago and use only that.
There are modern wick materials available, but I never found one that worked very well, but they do work.
You can try LiveSteamStation (Accucraft):

Or TheTrainDepartment:
There are probably others.
Not too sure what kind of burner set up you have, but whatever you use, try not to fill the pots too tight, or the alcohol will not burn very well.
Cheers,
