Not sure what the base price of the RS45 is for you. For me it was $2600. So $2200 more would not be worth it at all for me.
I agree with Bayne. There are so many setup discs out there to do what you want with a little time. Also, the RS45 won't get to a near perfect color since you would need an external CMS to get it right on the mark as the RS45 doesn't have robust CMS controls if you want to call them that.
Now, I own an RS45, but have only shot the image on to a beige painted wall, and the image was great out of the box. I see me making a few adjustments once I get it into the theater, but wow, was I blown away.
