<<How do you rate the 700ift?>>
I consider it one of the best 17" shadow mask monitors in the market right now.
<<Samsung's website says the ift can do a much higher resolution and better refresh rates I believe.>>
Higher res but not higher refresh rate. Both 700IFT and 700NF does an optimal of 1280x1024@85Hz, they both can also do 1600x1200@75Hz, but the IFT can go as high as 1920x1440@64Hz. I think the NF is also capable of doing 1920x1440, but you'll probably need a software like PowerStrip to force it.
<<The only other difference I see between the two is aperture grille and shadow mask.>>
Between the 700IFT, and 700NF, thats correct.
<<Another thing, with a dot pitch of .20 equalling .24 in AG terms, the 700 ift is very appealing.>>
Actually, 0.20mm horizontal dot pitch equalling 0.24mm diagonal dot pitch(diagonal is what really counts, but not associated with AGs), the AG's pitch, called grille pitch or stripe pitch, have a different set of standards. Right now all the AGs are below 0.25mm, with the Sony F series going as low as 0.22mm(mad expensive). Its very hard to compare the two different pitch standards, the shadow masks(all call dot pitch) use to be as high as 0.30mm and 0.28mm digonal, so 0.25 and 0.24 of today sounds very scary. As for AGs, they're all very decent because none of the are above 0.25mm.
<<Also, the 700ift is cheaper. Is there a reason for this price difference. THe only thing I can think of is that shadow mask monitors are cheaper to make. Am I right?>>
One of the reason is that Samsung produce the DynaFlat IFT tubes themselves, but buy the NF tubes from Mitsubishi. So I guess there is some kind of loyal fee there that makes the NF more expensive. And yes, shadow masks are relatively cheaper to produce because the AGs are originally invented by Sony, as you know anything Sony is expensive.
