There are LCDs without any blur (mostly the 120hz ones, but some 60hz ones are perfect too) and with
0 input lag. They do exist, but they may not be the best regarding colour accuracy and other things of course.
Also inverse (I call it reverse) ghosting is very rare and only happens on some bad LCDs - certainly not on decent ones nor on "all" LCDs.
And yes TN panels are quite awful. The area where no TN is decent is movies : they all look awful (unless you're like 2 or 3 meters from your monitor) and the colour banding is very very noticeable because they only have 6 BPP dithered colours and not true 8 BPP. Even a 1080p blu ray doesn't look perfect on the best TN panels.
The "pro" quake/ut players (who really need 120hz +) and such all say that 120hz LCDs run and feel as good as their old CRTs. They are not concerned about colours accuracy or movie watching however.
And yeh, have a look at plasmas although they are not supposed to be monitors, they are basically "flat CRTs".
Also have you tried all the other technologies like MVA or PVA?

I'm not satisfied with LCDs at all either, no flexible refresh rate, no decent resolution scaling, no decent colours and contrasts etc etc but I can't have a CRT, I move often and don't have a car (nor even a license) I won't carry a 30k's CRT in the train nor on my back.
So I just picked a cheap but decent TN panel (

... while waiting for better ones or new technologies to appear (ever heard of OLEDs, or SED/FEDs?).
I'm a Quake/UT player so I can say it feels perfectly responsive and "snappy". Of course 60zh means I get quite lot of tearing (I play my games at 100 or 120fps to minimize it without vsync) but ah well I couldn't afford a 120hz LCD and they have crappy colours and pixel pitch so that was a big no for me.
Colours are accurate by default but of course you get the TNs colour banding if you watch closely. Blacks are okay (they don't look blue or anything) and the pixel pitch is very good (closer to that of CRTs because it's actually 1920x1080 for a 21.5" monitor) - anti aliasing isn't really necessary if you play in native res.
Surprisingly, it has a
good resolution scaling (if you don't go below 1280x "X", otherwise it's gonna start looking blurry and pixellated). I didn't expect that but it's quite good because it makes movies in less than 1080p look still decent in a way, and games as well.
The monitor has a 4/3 mode (that can force even a 16/9 res to look like 4/3) which works fine for older games. What I did was create a custom res of 1440x1080 in the nvidia control panel - the highest 4/3 I can use on it - and then I use the monitor scaling thing and it looks and feels fine (nividia scaling has always been broken for me, it sometimes works but then I'll update my drivers and the setting will disappear...).
