There are sets on ebay, but they are shipped from Europe (which seems to be the case for any with clear coners). And for some of them you have to re-use your old bulbs and modules (if you have them)

BTW I saw someone selling a used pre-lci set on this site for around $500, which is a pretty good deal.
