I grabbed a couple of these from this seller off ebay
http://www.ebay.com.au/itm/280692958416?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
They arrived yesterday and I installed them on my Lensbaby composer pro with sweet 35 optic
and on my samyang 8mm fisheye
really well made and come with a really nice accurate little plastic locating template so you get the chip in exactly the right spot as well as some little plastic filler/spacers to bring the height up (which i needed on both these lenses.
I glued them on with araldite a 2 part epoxy glue that sets quite fast but not too fast allowing me to get the position just right, importantly the glue does not have vapour like superglue which could mess up the rear lens element.
I followed these programming instructions and it all went perfectly

I hope this info helps anyone else looking to do the same
