experiences with portable LCD TVs for classic micros?

TV has a max resolution of about 640 / 8 = 80
characters per line. There are extra factors...

   pulling the resolution down:
      sending the signal through RF and not a true
         video "monitor" jack will cause the loss of
         maybe 1/2 of total resolution.
      LCD's because they are small typically don't
         have all the pixels there anyway. 640 x 480 =
         307,200 pixels. Cheap small LCD's might use
         120,000 pixels.
      screens are typically "overscan", meaning
         the edges are clipped off and lost.
         Computers meant for home use were built for
         this and compensate.

   pushing the resolution up:
      your eyes and the screen work with analog
         information. Your brain can add some perception
         through signal loss, given a context.
         For example G00D can be percieved as GOOD,
         even though technically it's wrong.

$20? Jeepers, no big loss. Try one and see for yourself.
Bottomline I think 32 characters per line is pretty easy to
get through.
