You can of course try to go with the threaded suspension fork option, but there are some considerations there. First of all, I'm not sure if there are many (any?) quality forks offered with a 1 1/8 threaded steerer. If there are, then you hopefully are able to purchase one with as similar a size steerer tube as your current fork. If it's significantly longer you'll need to have a bike shop cut the fork and then cut in new threads. If only slightly smaller, then they would need to cut to length and then clean up the first couple of threads.

If it were me, I'd instead buy a standard threadless fork with matching headset, and a new stem. A little more upfront cost maybe, but opens up a much deeper pool of fork options.
