you mean computer monitor?
I have a 19" hitachi superscan elite. It's an amazing monitor... i've had it for many years. It's just as bright and crisp as the day i bought it.
Video monitor? I've got a Panasonic BT-H1390Y, which is superb. NTSC & PAL, blue gun, underscan, 16:9, 4:3, multiple video inputs, component input... it's great, but too heavy for field work.
Considering getting a new laptop to use with DV Rack for a super-lightweight field monitor/hard disk recorder combo...
