I bought the Urbini for $200 at Walmart. It is fantastic. It has a bassinet that turns into a stroller. You can remove the bassinet and put the carrier on it alone so that is not all big and bulky. It looks like one of the more expensive stroller systems but at a much better price.
We bought the safety elite plus. Or something like that from baby depot inside of Burlington coat factory. Good reviews and passed safety. Came with stroller and car seat for $180.
Do some research and read reviews. I went with a combo from Walmart, the Urbini Omni 3 in 1 Travel Set. It had the best reviews and was exactly what I was looking for.
Girl... They grow so fast i wouldnt put that much into one. Youll never get it back if you sell it. I bought one for 180 from babies r us.
