I would HIGHLY recommend the Maclaren double strollers. They hold 55 pounds per seat...even more! I have a Maclaren Twin Traveller (now called Twin Techno) and it is GREAT! I have a 5 year old and a 1 year old. I bought this stroller about a year ago and LOVE it! It folds nice and compact and DH worries about getting it on and off the trams. It has two baskets underneath, which is great. It has separate canopies for each seat and it also comes with raincovers, too. (and even boots for the winter months, if you want to use them!) It's a great stroller. You can find deals on ebay. I bought mine brand new for $160...and the stroller retails for $379!
