Smashed mudguard - where to get a new one?

[Digdug]

Some ******* has hit my bike while it was parked on the road outside my house (and, naturally, driven off without stopping  >: ). The front mudguard is smashed, there doesn't seem to be any other damage tho I've only been able to look at it in the dark.

Now, I have no idea how much a front mudguard costs or how difficult it'll be to get one for such an old model (gen 1 Fazer 1000, red). I've had a quick look on fleabay but there's none in the right colour, and I haven't even been able to find one by googling. Can anyone suggest where I could get a replacement one from and how much they are, either new or second hand? I've got a £400 excess for accidental damage so no chance of claiming it on insurance, so I need to keep the cost as low as poss.
