Recommendations please: Propeller compatible touch screens

Just looking for some recommendations from those of you who may have experience with a few different touch screen displays that work well with the Propeller. There are a huge number of them, from units that appear to need a significant amount of support circuitry, to "intelligent" displays that seem to only need a simple serial connection.

My applications will require a small display - 4 or 5", and a larger display - 10 to 12", full color (at least 256 colors anyway). I will be displaying only simple shapes, buttons, text and data - think artificial horizon with altitude, airspeed, etc., on the display, with some hot spots to switch between a few different screens/functions.

Just trying to save myself from spending a lot of money on something that sounds great, but is impracticable in Propeller-world.

Also - The propeller can't process external video, but can it be used in a video overlay fashion, or would I need something like the BOB-4?

Thanks!

    I have several of Rayman's touchscreens. They look nice and work well. But they are memory hogs. I've pretty much resigned myself to using a second Prop as a graphics slave whenever I add a touchscreen to a project.

    I believe Rayman has some newer screens with an added processor which shouldn't require a second Prop but I haven't used these myself.

    I have some links to displays in post #7 of my index (several of the links are to Rayman's touchscreens).

    A Prop Backpack will do video overlay.

    How much function do you want from your touch screen?

    I use discarded android phones, they do a LOT, and the price is ok, just takes a lot of looking.

    Yes, but both the video source and video display need to be NTSC. I'm not aware of any NTSC compatible touchscreens to use with the Propeller.
