FCP Finishing Monitors

I have a very small production company editing on a MacPro 8-core FCP system with Kona 3 card. Most of what we are doing right now is DVCPRO-HD downconverted to SD Letterbox for cable network delivery on Digibeta, but I suspect the show we're currently producing will soon deliver in HD.

I have been renting, but wish to purchase a finishing video monitor, but see there is an impossibly vast range to choose from. In the past, I have rented the Sony BVM multiformat monitor to finish some HD work, but that monitor is way to expensive to purchase.

I have been looking at the following LCD monitors:

Sony LMD-2050WHD 20" (w/HD-SDI kit)
Panasonic BT-LH2600W
JVC DT-V24L1DU

They all seem to be in the right price-range (under $4k), but wondering if anyone has any opinions about them. Can an LCD monitor really be trusted for decent/accurate color correction? I see that the LEAST expensive one -- the JVC -- seems to be the only one that bills itself as having full native 1920x1080 resolution. Is this some smoke-and-mirrors thing (like Panasonic's upconverting of 720p to 1080 on its older cameras)?

I have also heard good things about eCinema, but their monitors apparently won't be out until late-Fall.

Any thoughts? Other suggestions? A more price-friendly CRT?

Any help much appreciated!
