Interesting options, mostly out of the usual range of TVs... (10", 12", 14", 21", 25", 28", 32" for tube TVs).
My funroom TV is 14" portable - the picture quality is superb.
The back-up TV is a 21" - highly dodgy TV anyway.
The big boss TV is a 28" 100Hz jobby - I've not used the PS2 on it yet because it scares me.
Lower screen size = better resolution (generally)
