Try Sil-Walker in Camarillo, CA - they have a pretty good selection of stock 
membrane switches and kits.  Their button labeling is set up so you can use 
custom labels, and the switches seem to be good quality and reasonably 
priced.  Unfortunately you have to order by telephone - their web site 
doesn't allow on-line ordering.  Good luck with your search.
