Elana the basket,
You know what they say about opinions... :)
We got a similar one from Graco -
...and I love the mechanism for releasing it to fold up - it is MUCH easier than the other ones we've fooled with. From the pictures, it appears that yours has the same mechanism, which is good.
You might try to find a place to try them side-by-side. I don't find ours very heavy, although it is pretty bulky. I think I could get it into the car pretty easily, though. There were cup holders, and there's a place to keep your keys that's covered. I haven't had the opportunity to field test it yet, but my friend recommended it because it's the same make and model that she has - and she loves hers.
Graco is a good brand, in general. I think you'll be fine. Especially because of the release mechanism, it's great. But I'd try a few models to find one that combines space with lightness. I think it's more important to be able to get it into the car on my own than it is to be able to carry an entire week's worth of groceries in it! YMMV! :)
