Used to own Capella but I've got problems with the wheels... changed to peg perego. .. so far it has served its purpose. . Advice for you is to go for single wheel.. easier to maneuver. .
Just to share.. Im using medela sterilize bags.. a box of 5 cost ard $20 odd... but each bag can use up to 20 times.. very convenient.. just put all the washed parts in plus water and pop the bag into the microwave for 3 min! That's all!
