Slickone,
Hitachi 772F is flat shadow mask tube, Samsung 900NF is flat AG tube, cannot compare.
All NEC mon is really made by NEC, but the FE, FP series use Mitsubishi Diamondtron NF tube.
Samsung 900NF also uses Diamondtron NF tube.
The price of NEC FP955 and Samsung 900NF are similar, both are their top model.
Eizo is even better than Sony in spec, but it's the most expensive, because it's made in Japan.
I don't like Sony computer stuff too, especially mon, for the price of a mid-end Sony mon, you can buy a NEC or Hitachi high-end model. also for the price of a low-end sony mon, you can buy a NEC or Hitachi mid-end model.
If you can afford, get Eizo over Sony anytime, Eizo is the real professional mon.
LG is like Samsung, produces good mon at better price than Japanese brands.
LG 995E is the best buy 19" invar shadow mask mon in the old days, Eizo's 19" invar shadow mask mon is even better but price is double.
LG has new Flatron tube mon, they claim it's real flat inside and outside while Sony's FD Trinitron and Mitsubishi's Diamondtron NF is not flat inside, just with a flat glass outside, and it doesn't have horizontal tension wire as on Trinitron and Diamondtron.

Try to see the real thing first before buying.
I see a big problem on the new flat tube mon.
I see Samsung 900NF, NEC FP955, Sony's screen border is curved at every side, cannot adjust them to be straight lines no matter how hard I tried.
However, I see the cheap KDS AV-F series (use FD Trinitron tube too) have much better straight lines border.
For flat invar shadow mask mon, such as Samsung DF series, I see the borders are not perfect straight too.
For old non-flat invar shadow mask mon, I see the borders are near perfect.
