Where to Buy G9 Lens

Hi all,

So I like the G9 lens better than the G2 and I was wondering if there is any vendor who would sell lens from defective 7875 diodes. Been searching around but can't find any.

Also anyone knows where to get lens holders for cheap? I found an S1 lens from a group buy a few years but I am not sure where to get a holder.

Cheers
