Double Strollers

I really need advice on double strollers... I've started my research but I don't know where to go or what to do... I'm having Irish twins and when the new little one gets here in July I'll have a one year old. I don't know where to really start except I know with the closeness in age I can really get any style of double as long as I can fit a car seat on it. Please help? TIA
