2005 HID headlight assembly replacement recommendations

I have a 2005 with ~185K miles. The lenses for the HID headlights are foggy which is slowly becoming a safety issue. I have attempted several compounds to buff the lense with no real success.

I am interested in replacing the entire HID headlight assembly. OEM HID headlight assemblies are expensive. Does anyone have a recommendation for a aftermarket product that doesn't require significant modifications?

Thanks. Dean
