Depends very much on where you live. Most tomatoes I can buy make far worse sauce than canned tomatoes unless I am willing to spend a lot of money. And if I'm spending the sort of money I have to spend to get good fresh tomatoes I'm not 'wasting' them in a sauce. Hell even making sauce with the cheapest tomatoes in the store will no doubt cost me at least twice as much as using halfway decent canned tomatoes for a worse result.
