Agreed, Art's reviews are the best; however, I have read Art's review several times now but he doesn't compare it to the IN83 and without that comparison it is hard to judge. I think I will have to cross reference projectors he does compare the LG to and see if I can track reviews back from those projectors to see any comparison to the IN83 to try and determine if for instance usable black level's will be improved.
I have a bat cave if you will, meaning black ceiling, walls, and carpet..yes it is Dark and has almost 0 reflections to deal with so possible black levels are now only limited by the projector's capabilities. I also feel that my IN83 is now pretty bright; therefore, before I was aware of this LG projector I was thinking that a JVC RS15/25 may be my next projector and in fact is still high on my short list. Obviously each of these projectors will have their positives and negatives where the obvious high points being price and usable lumens on the LG vs. black level and motorized and more flexible zoom and lens offset on the JVC. Bottom line is I am not sure that the JVC is worth the $ for great black level while loosing the extra lumens that will be needed as the bulb ages.
Update: In yet another read I did find a reference to the IN83 in the LG review that Art did. I glossed over the HDTV and Sports section but in there the following is stated: "The IN83 was also bright, had the very best color, and was razor sharp. Perfect for sports. (The IN83, though had weak black level performance, not even as good as the LG.)"
It sounds like I will have some improvement in the black level performance which is good. I can live with and prefer the softer image from the LCOS machines as that razor sharp image causes some moire artifacts that I hope to improve with new screen material but should be eliminated with an LCOS projector.
