S.L.
I LOVE my Snugli Front & Back pack. Sometimes, it's the only thing for the situation! Especially when they're old enough to sit on my back! I could mop, vacuum, whatever, and the baby was as happy as can be. When he was cranky and wouldn't let me put him down, on the back he went and would often fall asleep. I could get him out without waking him up sometimes, too, or just lay him on my bed in the pack! But I used it mostly camping, hiking, airports/travelling(it's much more compact than a stroller), at sporting events (strollers don't work with stairs) and at home. Anywhere that was stroller-accessible, we used a stroller instead. It was $30 at WalMart.
I also have an Evenflo Take Me Too double stroller. I'm pretty sure it accomodates any infant seat in the back. My 2 year old sat in front until the baby was big enough to sit in front (it's easier to steer with less weight in front). The oldest has just outgrown the weigh limit of 40 lbs. I never would have been able to do some things if it weren't for that stroller! I took it to tons of stores, especially those that aren't kid-friendly because it kept my kids confined and portable. They had snacks and toys, and the back seat lays down for whoever was sleepy. It was $116 shipped from WalMart.
Another advantage of the stroller is the weight limit. I think the Snugli is just 26 pounds, where the stroller is 40. But tiny babies love being so close in the Snugli.
I guess my conclusion is that I would get both, if I could! I'm not rich, but I found both items to be well worth their cost, did lots of research before I bought them, and got them for reasonable prices ($150 for both). As opposed to a Baby Bjorn and Peg Perego version of the same items, which could cost you over $500!
