What are cheapest out of state schools?

<p>I’ve done a little research and it seems the cheapest OoS schools are what I guess could be called Tier III schools.
I imagine that the education is just fine at places like Penn State Lock Haven or SUNY Geneseo or 'Tiny in the Corner of Some State U."
But if you look, they all show about 98% of the students are in-state at almost all of these schools.
Why would I send my D 400 miles and spend $15,000 to $20,000 to go to some other state’s state school?
Sorry, I just don’t see it.</p>
