Old Shimano Deore LX/XT 9 speed is indestructible and works with old road 9 speed STI. That's what I have on the Thorn XTC. (26" wheels, yes they do come up on ebay, no not for supercheaps) and those bits can be had on Retrobike / evilbay.
Old XT mini-Vs seems to be very good, cantis also work but they can be a pita to set up. New Shimano CX cantis seem good and not too £££. I'm running Avid Shorty6, rear is grand but the front is always squaky...
A MTB will work just fine unless you want front rack braze-ons then it becomes a little trickier. Have an ask on Retrobike often mad bargainz there too :)
