By the way, I've got some really cool new transformers:
I'm going to use one of these for my kitchen lighting - these go for on the order of $15 a piece. 75W, and they're small enough they could conceivably fit inside a light switch!
If it does fit, I won't have to make another hole in my drywall, and I'll always have easy access to the transformer in case one does go out over the years
