We got a 2006 Sienna in March & love, love love it! The prices are very reasonable for what you get, barely more than the used ones we looked at.
Friends have a mazda mpv, and it is nice, but not as smooth and not as large (good/bad depending on your needs).
We also have a Honda Accord 2000, and have had several major problems (transmission, car's computer) but Honda has been great! They fixed 3 issues out of warranty.
One reason we chose the Sienna without even looking at the Odyssey is that we tow a pop up with it. Because the Odyssey has a history of transmission problems, and towing is hard on the transmission, we preferred the Toyota.
