Id also stay away from the 1200, because I know of someone who has had really serious headaches with FW. She'd fix one thing just to have something else get ruined with update.
The one really nice bonus is the Realta HQV. I'd have zero use for it, but I'm sure Im the rarity here.
Im a bit paranoid of all the companies in general as far as FW support for older models, whether that is some part of planned obsolescence or not. For example, I was happy to solve -5db LFE cut in my Pana BD-30 player, but AFAIK they never offered to fix a similar issue in the BD-10 player. While I do find Panasonic folks to be very good with FW support, I do think this BD-10 example is less than ideal for us wee consumers.
That being said.... FWIW... my BD player works as smoothly as smooth can be. One problem disc ever, Sunshine, with about 300 hours of only movies. Never tried it again yet. Its the only bad experience with over 50 Bluray discs played in the Pana. (However, don't ask me about my luck with HD-DVDs on my HD-A35... Bourne Supremacy, Assassination of Jesse James are two bad ones, or if I just leave the player on pause for a while...). But, OTOH, the Pana blows chunks with SD-DVD playback, while the 1200 has got Realta. Then again, at least my HD-DVD does something decently... SD-DVD playback.
We can't argue with money. $50 is still $50. $100 is still $100. But peace of mind is priceless, IMO.
