I'm glad you feel that way as I completely agree. The Famulator is a BEAUTIFUL Famiclone, by far the best looking one I've seen.

I can't speak highly enough of its controllers. They are very comfortable and put many other Famiclone controllers to shame.

Still if you don't like them or in your case would rather simply use an NES pad, the DB-9 Famiclone standard has been documented by nesdev, so it is possible to build an adapter to use standard NES controllers.

As well, the new stock Mayflash NES/SNES Controller to Wiimote adapter now come with a DB-9 to NES 7 pin adapter. I've ordered one of those and when it arrives I'll let you know how well theirs works.
