If you want rigid, lightweight and corrected for 80mm travel, look at these:
I've had the 100mm version for a couple of years on my winter commuter and it's great - some flex gives a comfy ride (I'm a roadie so with either ice tyres or 26"x28c Gators it feels so to me!) but for road use they are so much better than the old sus fork and the weight shed was over half a kilo for me, on my old Rockhopper conversion. It means I can climb unseated without that unpleasant-feeling power loss into the front suspension.
Also sold for twice the price under different brands, can't recall off the top of my head but you might Google it if you're interested.
For discussions about bikes and equipment.

The suggestion of another bike is also appreciated and does make a lot of sense.
The Mt Tura is about 1.2Kg but you will loose a little when you cut the steerer its huge, most steel forks I have seen are about 1kg but that was for 700C a cheap suspension fork is about 2.5 kg
Sorry for my late entry in to this conversation, but I have only just noticed this thread. I have uploaded a snap shot of my bike. It is a 2006 Kona Lana’i. Th original forks were cheap spring-only shockers with 68mm travel. After doing all the recommended measuring the nearest fit to an ideal rigid replacement proved to be Surly 1x1 forks designed to replace 80mm travel suspension. Because of my brake system, I needed V-brake only forks; disk fittings would interfere with the reaction arm on my drum brakes. Surly 1x1 “cantilever” forks proved to be unobtainable in the UK, so I ordered them from Jensen USA in California and they were delivered to my door in Scotland in four days at a reasonable price. I took them to my local bike shop to ask them to fit the star fangled nut. We chose not to shorten the steering tube so that I could mount the handlebars in a more upright position.
It rides pretty well. I use it for supervising youth groups on Duke of Edinburgh type expeditions, so it is mainly forestry gravel, minor roads and Sustrans type tracks.
