Shift fork, Synchros?

When driving home from work I banged 1st to 2nd gear (driving like a jackass of course) Anyway. I lost 2nd gear, just grinds and won't go in and I can't go to first without coming to a dead stop.

Would this just be the 1-2 shift fork? If so should I change get new synchros as well? How much would you guys estimate a shop to charge for that?

Thanks
