I've been having trouble deciding between an LCD or a monitor. Add to that the fact that the width of the inside of my cab is 26" and all of the 27" TVs I've found are slightly too wide. So, I decided to go a little smaller. Turns out that 25" LCDs are difficult to find in 4:3 Ratio... they all seem to be widescreen format these days.
Some more digging on craigslist.com found me a 25" Sony monitor. This thing is a monster... very heavy. The dimensions work (I'll have to cut some of the back off my speaker shelf, but no biggie) and the picture quality is outstanding. I connected my laptop and ran a few games on it to see and I'm definitely happy with this choice.
Now, I've got to reinforce the monitor shelf some more... did I mention this thing is HEAVY?!
It remembers its settings when power is lost and has just about every type of video input on the back (see image). No speakers built-in, but that's what the Klipsch 2.1 system is for...
