Just wanted to post a positive review of a company called Air Handling Systems in Connecticut. I picked up a complete spiral pipe & fittings dust collection ducting system from them this morning and had a very good experience.

I ordered all the parts (85) online yesterday morning, got a call yesterday afternoon that everything was in stock, and picked it up this morning. Everyone was very friendly and my order was already pulled and waiting for me. Their web site is extremely easy to use and has lots of good information. Their employees also seemed very knowledgeable and offered some suggestions for alternative parts or parts that I needed but didn't realize I needed.

The quality of the parts seems to be excellent - smooth welds, tight tolerances, etc. Prices were competitive with other online sellers.

Based on this experience, I highly recommend them, especially if you can drive to the New Haven, CT area to save on shipping. If you can't, they ship internationally.
