I agree mfrey, it will be more than a few years, hopefully, before I will be in the market again. My 42 ST30 is doing just fine in the bedroom and the VT25 in the family room is just superb. Once I tinkered with the ST's settings with the help of the folks over on the ST30 DYI Settings thread, I was able to get it to rival the VT25. I have happy campers in both rooms of viewing.
Yes, the ST was a bit dark. It was quite evident when leaving the VT25 to continue viewing a program on the ST in the bedroom. Not fun at all. The DYI settings changed that for me and hopefully for others. I do think that a Pro Calibration is a must for the larger screen ST30s. No if's, and's or but's about it. Give up a few beers or new toys and get it done. It will be some of the best money you ever spent. You will be amazed day after day and each night with the PQ these new plasmas can pump out. I will be lurking here as long as the thread pops up on the front and will help if I can.
