Yep, repair price sounds about right. I presume that includes a respray after repair?
However, I just replace a 2003 fox eye fairing on mine, paid £180 for genuine one, full painted. The older square eye fair is a spot more, £210-220 ish. Note that doesn't include stickers or front badge. Pair of stickers come in at the bargain price of £70...
Now, TBH, that's still a pretty good deal, Yammy used to charge £450 odd for the front cowling until last month!
A knock off fibre glass fairing will cost you about £120. However a decent spray job on that will set you back a further £100 odd.
If you decide to street fighter the bike and lose the fairing, you're gonna have to fork out some cash for replacement headlights and a tidier mount for clocks etc. Probably ain't gonna work out much cheaper TBH.
So, ultimately the best/cheapest plan is to phone your local Yammy dealer and order a new fairing sprayed to match. Then swap it over yourself (dead easy, 1-2 hr job).
