Should I take my fancy stoller on the plane or buy a cheap umbrella stroller?

I don't have a stroller - or a baby - but I travel a lot and I've seen lots and lots of fancy strollers on planes. If you are with a baby (with or without a stroller) they'll let you pre-board - that's go on the plane before the rest of the riff raff. They'll just check the stroller and stick it under the plane and give it back when you land. I haven't ever seen a really damaged one come back up after a flight...

I would take a umbrella stroller, unless your fancy stroller is super lightweight.
