Should be a sheet metal fabricator near you. Go there and tell them what size pipe you want. Have them roll it out of 20 or 22 gauge stainless steel. It isn't cheap but will last for decades and is a lot safer than galvanized pipe.

Have you been using the "blued" or black single wall pipe? The blue stuff sure doesn't last very long (about a year), the black is a lot thicker and will last much longer. However, like white17 mentioned, stainless is the way to go. They do manufacture stainless snap-together pipe in the same diameter as the black and blue types; you just have to look a little harder to find it.

Yukon - I didn't know Canadian tire had that type of telescoping pipe. I can see that being real handy, thanks for the tip.

As mentioned multiple times stainless is the way to go unless you intend to just use it for a year or two. I got a dozen places with stainless as I got fed up years ago replacing constantly. Pays for itself over the years easy. The one thing you need to watch I have found is to stay away from all the different pipe systems sellers have that don't often fit together with each other. I go to a sheet metal fabricator in Fairbanks and he makes up standard old fashion stainless crimped pipe that fits all together with each other. The fancy wood stove stores are often selling these different style and sizes even though they all call it 6" pipe means nothing. They change their brands all the time also and played heck trying to fit them together.
