I believe it came out to around $65 per set (2 belts), including chroming the buckles. It was a few dollars to re-color the retractor boots, and a little more to re-chrome one of the retractors. My total bill, including shipping, came to just over $300.00, but I did not have her transfer the original cloth labels, which would have been something like $5 each, and I also had some credit back for the extra pieces I sent.
I went with a very basic job just to get them looking nice for the new interior, but I think she offers other options depending on your level of restoration.
