Where can I buy high quality Gloss Black Kidney Grilles

I just purchased my first e46 (2004 330i ZHP) and very much want to change the stock chrome grilles for gloss black however, I am having a very difficult time finding an available set. While I have come across sets on eBay and Amazon, I think you can understand my desire to find the best, closest to OEM quality as possible. Genuine BMW black gloss grilles seem to no longer be available anywhere, and I have even scoured various websites in Europe...
