In reply to bigbobbyking:
Sorry - should have added that, from experience of the Suntour XCM forks on my sister's old Trek 4300, RIGID forks would be an upgrade! They'd be lighter, stiffer and have about the same amount of travel!
Admittedly, that was a few years ago and on a 26" bike.
Edit - apologies, I think they were actually RST forks, but the comment probably still holds.
Are these any good to you - slightly short travel, but prob the same as the XCM?
