I HIGHLY recommend the Beaba Babycook. You can find it at Bumps to Babes. It steams AND purees all in one machine. It sounds like the Chicco one tallmama recommended above, but you don't have to put the blade in since it's already in the machine. There's a demo video on the Williams-Sonoma site. It's great!!!
