When in that position, I tracked down a very high quality used full CF fork for about 75, it had some cosmetic imperfections (very minor ones), but it still beat spending 300+ for the same exact fork from a store, YMMV.
You bike needs are different from mine , obviously.
hope the seller didn't damage the CF fork before flipping it. ( wishing good luck in the future)
.. to having an alum frame/carbon fork fixed gear,..
I might even have a bike I've owned since before your first birthday..
