Blondeshavemorefun I feel better thinking someone spent that much on a pushchair for 1 (and that it was ugly!) this one is at least v well made - all steel frame, so you can leave the child in the top seat and take the ones out from the underneath seats without it tipping - v clever!
Also on different days I have 1 (DS), 2 or 3 children, so this becomes a single, double, triple as needed (so I can sell my Phil and Teds).
nannynick - yup those extra cm really make all the difference!
Our outside front door used to just be an opening, so it has a narrow door in it (about 71cm?) - I was hoping I could fit a double in by angling it, but it wasn't happening...
Starberries Um... different ages on different days:
Mon: 1 yr & 23 mths
Tues: 1 yr & 2 x 23 mths
Weds: 9mths & 2 x 23 mths
Thurs: 9mths, 15 mths & 23 mths
Fri: 9mths, 15 mths & 23 mths
My feeling was that the toddlers are too small for a buggy board and the babies are too big for a sling - I have friends who use both and they said buggy boards are good whilst kids are in the right mood (not if you're in a hurry or need to use a bus or if they're having a strop) and the ones with bigger kids (3 mths +) with slings and pushchairs are hunched over like Quasimodo!
I was hoping that the buggypod would be the right (& cheaper) answer, but its just not stable enough to be reliable... :(
thebody et al, oh go on, you know you want to. 
Can you tell I've spent way too much a long time thinking about buying this wretched thing!
