Bish
I make my own, i find the engraved brass one expensive in the UK and by doing my own i can add peronal touches. I just make them up on paint.net and print them out on card. I then cut out a piece of balsa to match the card, stain it, cover the card in fablon and attach. Here are a couple of mine, as you can see i add flags and emblems relevant to the subject.
I, too, am a big fan of Bish's method. With the ease of computer graphics, you can rather easily do some quite striking name-plates.
Here's my personal favorite---from a sadly now-defunct Lindberg Bismarck---showing a 'before and after.' All done up in a few minutes in nothing more complicated than MS-Paint:
