Yeah. Still way less. Has it BYU always been cheaper?
Don't know. I could probably approximate BYU's tuition prices for the past decade or two, but I don't know the other schools' prices.
(quick search) Here's some very good info on BYU's costs:

I remember when tuition went up to $1100 (1994) and many students were outraged at how expensive it was getting. I just laughed because they were very out of touch with the rest of the country. BYU's been an amazingly good deal for a long time.
