Corresponded with him a couple of years ago regarding refurbishing some standard gauge track. His prices seemed reasonable, but the deal fell apart because the cost of shipping the track to him (and then back to me) was prohibitive - it was far cheaper to just buy new track. I wish you luck, but track is bulky (higher cost) and transformers are heavy (even more $), so you might make very little in the end.
If you have a relationship with a company that does a lot of shipping, maybe you ship through them and get lower rates.
