the school you choose should not be based on how much it costs, it should be based on what you get out of it.
yes, i would research the school before attending, but like I said it depends on where you want to go, not where someone tells you to go.
I went to a community college, earned my AAS in Culinary Arts. I have been a chef for 40 years, and I liked my teachers too. played softball with some, and even hated a few.
