I think you might still need to supplement the tomatoes with paste - it has such a concentrated tomato flavor that the sauce kind of needs. Without it, as you've said, sauces end up kind of runny and bland.
This is one I use for a VERY basic sauce (that you can add your own tweaks to) - it calls for canned tomatoes, but good ripe, skinned and seeded tomatoes should also work. I have only ever halved the recipe - the full recipe makes too much for my needs: rouxbe.com/recipes/1202/text?tab=recipes
Also - drizzling in olive oil (as they recommend) at the end is really a nice touch.
We usually use whatever tomatoes we have (although find that based on how juicy they are, you may need to trim back on the time in the oven), and have tried white and red wine but prefer white.
