Dave- thanks for the link. I figure the folks in the dust collection business buy their ducts from suppliers like that and then double the price and sell it to us.
Since I bought my DC, I have been paying attention to HVAC ducting wherever it is exposed. It seems to be the current style to have no false ceiling these days. Anyhow - I have been seeing the same spiral sheet metal ducting that I bought, thanks for a link to a source. It will be saving me some cash.
Appreciate-
D
