Affordable and dependable Lightweight strollers?

Well I know my little one is not here yet, but I'm starting to look around for a good lightweight stroller. I'd like it to be under 100 dollars if possible, and something that my baby will actually be comfortable in. I know I may be asking to much. I've looked at several websites, and I have a couple in mind, but I was curious what you all have used. If there are any brands I should stay away from, etc.
