Pilgrimage

I have a stone cracked passenger side headlight on my classic '98 impreza.
I have found out the new part from Subaru is £180 ish and have looked at the quad upgrades (seem to be £150 ish for the Angel Eyes & £250 ish for the subaru upgrade (Morette?).
I don't really like the quad conversion and have searched everywhere for a 2nd hand lamp, but with no luck.
Can anyone help/ suggest a solution.
I really don't want to pay £180+ to Subaru for a new one!!
The problem i have found is that the light is the facelift model (ie shaved bit of the glass nearest the grill) and has the electric trim adjustment.
I am really need some assistance with this one...
