The best deal I could find was $148 front & $120 rear each at LTB Autosports with free shipping for the 8641-1038 Front 8040-1035 Rear combo.

I called Koni earlier this year to find out costs for rebuilds and they were more than buying new so I've been on the lookout. I'll hold these as spares for now and probably replace before next season as I think mine are getting a bit worn out.
