Vent hoses.

Im looking for a site to purchase a good exhaust fan hose i guess you would call it. The silver tubing with the wire running through it. Needs to be 6 inch in diam. Ive been getting them at home depot, but they usually last two weeks before they fall apart and require patching. Where can I purchase some that will last? Thanks

something like this?

This is the new shit that people should be using. No more pinhole leaks like the regular aluminum duct. Stops all smell and air leaks from coming thru the duct itself and stinking up your rooms.
