I have the Graco Snugrider with my Graco Safeseat.
I LOVE it. (except for that now I need another stroller as my son is wanting to sit up in malls, etc. and its not NEAR so easy to decide on a followup once you get used to the LARGE basket on the Snugrider!)
I find myself looking at my friends' BabyTrend Snap and Gos, envying their more accessible stroller baskets. (I can't put my stuffed diaper bag in my basket with the car seat on it. The other basket seems to be more "Forward" so it can still be accessed) OTOH, it is nice that I don't have to worry about "strapping" the seat in. It clicks in and comes out similar to how it works in the car.
Warning: remove the cupholders before sending through the airlines. We lost ours at gatecheck over Christmas and they're a bit pricy to replace
esp. compared to the cost of the stroller itself!
It folds easily, and very small.
As for the diaper bag problem? I ended up getting "Stroller swivellers" from Babies R Us and hanging one on the handle. Then, after putting the baby in car seat in the stroller, I hang the diaper bag from the handle. (The car seat alone is enough weight to counterbalance my diaper bag, so it still works if I need to pick the baby up). Just have to remember to remove the diaper bag before removing the car seat
Otherwise, the stroller tips over when the car seat is removed because of the weight!
Another slight negative: When folding it down, I seem to always be brushing the "Seat" part of the tubing against the ground. Not a big deal yet. But I keep thinking "if it was muddy, this would be a MESS"
But If we end up having to get rid of this one after this child. (if he's grown out of the Safeseat before we move to Texas we have decided it is not worth moving because of the low cost to replace), I will get another one for the next child, easily
Good with turning? Hrms. I consider it good enough. Occasionally I will have a turn sharp enough I can not make it so have to go over two aisles then back to the one I want. But not often. When I have to pick my son up out of the stroller, I can still push it with the other hand (albeit having to be a bit careful. It would probably be easier to one-handed steer if I thought ahead before taking the son out of the stroller and made sure the front wheels were straight, then locked them since my main problem is the front wheels going all over.) It is NOT as easy to steer as a Maclaren. But easy enough that I have never complained about steering two-handed, and I quickly got the hang of what to do to steer it one handed. (though I try to do that minimally because it is more difficult)
Good storage? AWESOME storage. One of the things making it hard to find another stroller because most strollers don't have this much basket. I've been spoiled!
