I have some original forks for it but they are the steel ones off the cro-mega. Try asking on the wanted forum for some. I know some people have used cannondale rigids on them also. Alternatively you could drop it to 1 1/8" using a chris king 1.25-1.125 devolution headset (pricey new mind), this will make forks and stems easier to source.
For cheap thrills polish it back to alloy like the al-mega XTR (see the scans forum) or powder coat cobalt blue (al-mega DX)/ gloss black (al-mega XT) usually costs around £40 per frame and forks.
Think you got the frame for a very nice price too, i'd sell off/swap the extras to recoup your outgoings/get period parts. If your on a budget plan your build to the component otherwise you'll end up with loads of stuff you won't use. A donor bike might be worth thinking about too (ie a £100 bike with full DX/XT, take what you need and then recoup your money by selling off/swapping the frame and other bits you don't require).
Let us know how you get on.
