I have been given a Bruin one from Toys R Us & it's TERRIBLE! I think it was pretty cheap, but it was so hard to put together (took me 3 goes - the parts just don't fit together properly & the instructions are unclear).

If I had been buying for myself I would have gotten the Fisher Price travel one that just straps to a dining chair. I like this one because bub can sit at the table with you, the tray is washable, it's hard plastic (= easy to clean) & it's cheap (about $60 at Kmart).
