I'm absolutely loving it. This is my first PJ system, but couldn't be happier. To be honest, the color oversaturation doesn't really bother me (read I can't exactly see it!), but it's nice to be able to tinker when you're bored.
I've got nearly 500 hours on the pj already and I'm still in low lamp mode, granted I have a rather small screen (92"), but the brightness situation was something I seriously worried about before pulling the trigger.
I agree about the sharpness on these machines, it's at the point where the source material is the limiting factor. Some blu-rays are noticeably softer than others. Being able to see the limits of the source is an odd sensation with the PJ, but I remember a similiar situation with CDs when I finally acquired higher end speakers. There hasn't been a person to see it yet that wasn't blown away by the picture, I know you're going to love yours!
