I ended up getting a super cheap one at Target - only $12 or so! I started off with a Space Saver High Chair (too high chair-like), then tried a different booster (too tall, so couldn't push the chair it was attached to in/under the table when not in use), then I found the Target one and it's worked great. I also think the Baby Bjorn one looks nice, but there are no straps to buckle your little one in & at almost 18 months old, my son still needs that. My favorite, though, is the Cooshie Booster. My daughter used it and as soon as I'm comfortable with my son not being buckled into a booster, I'll move him to that. It's so easy to clean since there are no nooks & crannies for food to hide in (which is also why I like the Baby Bjorn booster). The material it's made of really "grips" the chair well & it doesn't have straps, which makes it very portable too. Sorry, kind of a rambling response but I've just been through the booster search, so wanted to share my many thoughts. :) Good luck!
