I like both of your points. The Sindoh printer I used at my old job had a leveling assist function that told you how many turns of the left and right screws were needed to level the bed. I'm guessing this feature wouldn't work with a 4 point plate. However, I can see where if you already have a method using one way, the other might seem foreign.

Thanks for the extra info on the K-N-P too. Seems like a too good to be true price / performance combo. I'll have to see what I can do to get the wheels moving quick on one. At that price, they have to be running out of stock soon.
