I have not looked closely at current offerings, but a general comment:
you want one with a controller.  Driving many-pixel LCDs is a serious
hassle, and doing it yourself is not going to be worthwhile.

Well, I don't think you'll find *any* microcontrollers with RS-232 inputs.
(Remember that RS-232 is typically at least +-9V.)  If you're willing to
settle for *serial* inputs -- that is, what you get out of the TTL side
of an RS-232 receiver chip -- most modern microcontrollers have them.
The MC68HC11 is a nice chip in most ways...
