Been and done.
Secondhand forks are out there, just takes time to find them.
I was 9 months between the crash and the bike being road legal again. As the forks I got were Speedie ones I did the brake upgrade too. I paid for a service on them too, and it was still 1/4 of the price of a new set.
My insurance estimate said that the frame would need replacing too, but that's a lot of work. My dad and I did a number of things with a spirit level and a broom handle and concluded that it wasn't. From the 3 miles I've done since the rebuild it doesn't feel bent and doesn't pull to one side. Though ask me again tomorrow evening.
My advice as some one whose been there, if you can rebuild. There's nothing more satisfying than seeing a bike that was written off back on the road. If you can't still buy it back and strip for parts. You'll make far more that way than you paid for the salvage. (I paid £500 for the 'salvage' of mine, I was offered £1000 over the phone by a breaker...)
