Just buy new cassette wheels (they're a superior technology anyway!) and enjoy the extra gears. A 9-speed hub is 4 mm wider than a 6-speed hub, but you can easily fit it into the frame with a bit of squeezing. I've been doing this on my commuter bike for over a year and it works fabulously.
Nashbar has a sturdy commuter wheelset for $120,
