Hi
I’m thinking about a LQ121S1LG75 (generic, the original was SHARP) which can be found on ebay or aliexpress for around USD 110 including the controller.
It has WLED background lighting, is brighter and has better contrast and viewing angles as CCFLs, but it would need a (small) modification to the Picade and it is only SVGA (800x600).
See also my new thread about that.
Regards
Patrick
