I'm hoping some of you Spyder owners are on the RS-1 pre-buy list.

I searched the thread for RS-1 and got no results so if there is a long discussion please point me there.
My question is given the somewhat limited user available calibration adjustments does it make sense to buy this calibration system or any at all assuming JVC never enhances the calibration options?
(There is a lot of chatter around JVC eventually giving access to the LUTs and some hope of getting RGB cuts and gains but if we don't can this or any other calibration software do much to dial in the gray scale and improve the picture?)
Thanks for your time, LylePDX
