Hi S.,
I got a Phil and Ted's Sport. I have a 21 month old and a now 3 month old. Love it. The only bad thing is that the brake is a little sucky. (For lack of a better word.) You need to kick it up with a little force in order to disengage it. No biggie as far as I'm concerned. It maneuvers well. Both my kids like it. I even propped my Graco carseat into the top and had my 21 month old in the bottom seat. Not recommended, but it woked for when the little guy was sleeping and I didn't want to disturb him by taking him out of the carseat and putting him into the cocoon.
Speaking of which...
If you do go with a Phil and Ted's and are interested in a cocoon (it's for putting newborns in when you lie him/her down), I have one in red. I bought it brand new on Ebay for $20. It is in perfect condition. You can have it for $15. I can send you pics if you want or we can meet in a public place and you can see it. I think they sell for 30 or 40 smackaroos. We're a smoke free home and I always put a blanket down before putting my son in it. Honestly, it's kinda a must if you are going to lie a newborn down in the stroller. Email me privately if you are interested. Although it is not specifically for the Sport version (I don't believe they make one), it does fit in perfectly. It just does not clip in. However, I don't understand why clips are necessary. The cocoon doesn't move a bit when it's laid down in the bottom of the stroller.
Email me privately if you're interested.
Thanks! And good luck. Phil and Ted's is the cat's meow! ;)
