Hello,

Thearender is €295, and Colimo is another €129, it might be worth it for your product application to quickly change finishes. Colimo works with a range of products as well. I realize it's still a chunk of change, especially if you are in the EU and need to pay the 23% VAT.

Apparently an GPU/OpenCL solution of the product has been started, which is probably good news for all:
