I have about $2500 to spend and am looking at either getting a used RS20 plus a used anamorphic lens or getting an RS45. I have read about the motion issues on the RS20, but I'm not sure that I'll really care (I haven't seen any compelling evidence that suggests this is something a non-videophile would notice) about that. If you had the option, and could get either combination for about $2500, which would you take and why?
Here is my room specs:
Light controlled garage
120" 2.35:1 screen (about 96" 16:9 if I recall), currently white but could be painted grey
Room dimensions are 20ft^3, so not really any restrictions on the placement
Another option is the RS10, and save about $500, which I could use to buy a spare bulb or another cheapo mega bright projector for sports watching and gaming. I also don't need the CMS on the RS20 since I'll be using an HTPC which has a graphics card to do the CMS.
