i have the valco, its wonderful, i love it. and we never used the 3rd seat, when my 3rd was a newborn, he sat in the infant seat (carseat) facing me, which clipped right into the stroller with the adapter they sell, and there was still plenty of room for one of the other kids to sit in the seat facing him. when he got bigger, they just sat together. my kids are now just about 8, 6, and 4, and we still use it all the time, all 3 sit in it. its a great stroller, a serious piece of equipment. the only thing that is no good is that it is really heavy and awkward to lift, especially if you are shorter. im 5' 4" and its hard for me to lift, my sister is 5' 8" and its much easier for her, she can get her arms around it. however, since i keep it in the back of my minivan and just flip it in and out, i never have to lift it, so its great. it does get through a standard doorway, barely, but it does. it turns on a dime, you can steer with one hand, it goes on grass, gravel, etc,, even sand with some effort, you can jog too. the seats recline flat, my oldest was 2 when we got it, he used to sleep on his belly in it, probably for about 2 or 3 years. great for diaper changes, etc. folds up so easy. incredibly sturdy, i sat on the foot of it to breastfeed for years.it has individual shade things, which sounds trivial but its really nice to have. its definitely huge and awkward at times, but anything that is gonna cart around 3 kids will be, and i really think this is the most user-friendly of the bunch. it should be for the price, sheeeesh! oh, and get the $20 cup holder, also ridiculous, but so worth it. we have been living in this stroller for 6 years now, i use the hell out of it, when the skin was just too beat up, the company sold us a new one for a great price, and the whole thing is like brand new. nothing has ever broken on mine. love it.
