There's also the SunPak 6400 tripod on sale for $16 at Buy.com, includes multiple bubble levels. B&H sells this for $30.
Personally, I'm saving my dollars for a much sturdier tripod than either of these two inexpensive models. Blurry photos due to tripod wobble is evil.
The Dolica is so much better than this SunPak. This is coming from somebody who owns both. Well the sunpak has been thrown in the trash after the head snapped right off of it. Never again will I go with a plastic head of any kind.
