Previously we've made a few control panels that use a small (2x8) LCD=20
and 4 tact switches.  They work fine and are mounted into a horizontal=20
light switch plate, but don't really look all that attractive and are=20
fiddly to assemble.

We've now been asked to quote on making something functionally similar,=20
but with a touch screen.  This will do away with the current buttons and=20
add the possibility of more functions with soft keys.

I can see two ways of going with this.

1) An off-the-shelf controller like the CuTOUCH panels=20
(http://www.comfiletech.com/ct1721c.aspx) that we've used for more=20
industrial applications.  They are however a little expensive, fairly=20
bulky and look out of place in a home or office situation.

2) Some sort of LCD / touch screen module with either an integrated=20
bezel or can be mounted without too much hassle.  Maybe a PIC based=20
board would piggy back onto the LCD.

As these are usually only required in small quantity (anywhere from 1 to=20
20 at a time), I'd rather just use something that I can program in a HLL=20
(Basic, C, etc) and not fiddle around with all the low level graphics=20
and touch stuff.

It doesn't have to be a $50 solution.  Screen size of a few inches=20
diagonal would do.  If it could fit into a standard Aussie light switch=20
plate that would be ideal in some ways, as others can install the=20
mounting during building construction.
