To help settle this ego contest on leasing rates, here are some figures from 2015, then updated in 2017.
As always with figures, you can make them say what suites you, and one could argue that you could get 2 319s for the price of a 190/195, but certainly old knackered frames with questionnable reliability and reduced seating layout. Then from a commercial/product point of view...why would you?
Conversly, you can get 2 old 190/195s for the price of a newest 320.
Interestingly, ATRs can be quite expensive too.
