right now i have the peg perego aria twin - very compact but wide and the wheels are pretty crappy. it works with my 20lb twins, but even in parking lots it's not great. we have this model

but the new ones have the front wheels in-set

i would totally pay the extra for that as it will make doorways way easier.
we also have our "big stroller" which is the graco quattro tour duo. i really like it but it is kind of huge and falling apart. we plan to run it into the ground though and possibly buy a second when it's dead. we can use it for our babies or our older kids (3 and 4) or even with the 3 year old in the front and the babies in the back together.

here's my 3 kids in it

our 3rd seat is the eddi bauer tandem seat. it is so compact and folds up like an umbrella stroller but it's about as sturdy as an umprella stroller. it has small wheels like the aria and the front seat does not recline at all.

if anyone finds a magical solution (besides travelling back in time to buy one $700 stroller instead of 3 $200 strollers) i would be glad to hear it.
