Need Recommendations on DOUBLE Strollers

With a toddler and a baby on the way, I am looking for a double stroller of some sort that will fit my Graco infant seat. I would love some advice from moms who have used the sit-n-stand variety and/or the standard double seat stroller. I have been looking at the Baby Trend Sit-n-Stand, Graco DuoGlider, and Graco Quattro Tour Duo, but am open to other suggestions. I DO NOT, however, want to spend a ton of money on it since it will be used only occasionally. What are the pros and cons of the different types? Is there a particular brand...
