Hey guys, I received my HD72 yesterday, and finally set it up today. This is replacing my H31. I would of set it up yesterday but it wouldn't work with the mount I made for my H31.
Anyways, I'll start with some of the cons of this machine. First, I really don't feel it is a $500-600 step up from the H31, but I am keeping it anyways. Why, you may ask? I don't know, I think it has mind control over me. Seriously, though, I'm watching the opening ceremonies of the Winter games right now and I thought I would see a tremendous improvement in HD over my H31, but the improvement definately doesn't knock my socks off. This unit is also alot larger than my H31, and the mounting holes are off-center of the unit, which is why I had to build a new mount for it (my old mount had the plate made of plexi-glass and I was afraid that it would crack because of the pressure that is being put on it b/c off the off-center mount, so I rebuilt it out of 16 guage steel). The TrueVivid and AI modes do a whole lot of nothing. Those are about the only negatives I've found.
The pros are as follows:
1) I for one, love the brilliant color feature. I have mine set to 6 right now and feel that it really makes the image pop.
2) I threw in LOTR to see how it handles DVDs (since I've watched this movie more than any other I felt it would be good for comparison) and was expecting the image to be not as good as the H31, since it has to upconvert the image, but I was thoroughly impressed. I think this is what is convincing me of the $500-600 upgrade. Honestly, I've never seen the movie look so good.
3) This image is also much brighter than my H31, which helps during the day, since the projector is mounted in my living room.
4) I like the way the iec connector fits in this unit more than the H31. I assembled my own power cord out of 10 guage shielded copper and I had to grind off part of the housing of the female end of the iec connector to get it to fit in the H31 because the male side was so recessed in. The HD72 is not really recessed at all.
5) Not a biggie, but I like the remote better on the HD72 as opposed to the H31. The color matches the unit and it is layed out a little better.
6) Although the the image on high-def is not as great of an improvement over the H31 as I thought it would be, it is still a noticable improvement.
7) The slightly larger offset helps me out with my cathedral ceilings.
All in all, it seems like a great unit and by the way, I haven't had a chance to calibrate it, yet, so I'm expecting the pros to further outweigh the cons once I'm all set up.
