I have been buying flies from him for the last few years. Flies and hooks have held up well and the owner is a really great guy. He will tell you more about the entomology of the area you are heading than you need to know. I will be buying from him again.
The owner Peter, has a great stock of fly's. No issues with quality or price. He works out of his house in Littleton or the kompound in Littleton just off Broadway one weekend each month. He mainly advertises in Craigslist.
