If u really want the best picture quality get a CRT monitor like the Nec Multisync Series. There are 35 and 36 inch TV's made by NEC.
Models are :
XM37 Plus - XM3760- 35"- 65khz Horizontal Max - 1280x1024 - 1080i, 720p compatible
Has 2 S-Video/RCA inputs, 1 RGB input and a VGA input
XP37 Plus - XP3790 Same as XM37 Plus but has a 95khz horizontal max (1080p and up to 1600x1200)
XM37 Xtra - XM3761- 36" viewable, Same as XM37 Plus model but it has Component inputs and a 70khz horizontal
XP37 Xtra - XP3791- Same as XM37 Xtra but has a 100khz horizontal max frequency (QXGA and 720p at 120hz)
You can also check for Mitsubishi Megaview monitors.
There are these models:
XC-3716C - Megaview 37 Older model but really great monitors, has S-vid inputs, A RGB input and a special sort of connector which in real is VGA but requires an adaptor. This TV supports only 40khz horizontal (1080i max and 800x600 max)
XC-3730C - Best Megaview made - 85khz Horizontal http://vbp1.com/ecat/img/pdf/5268-XC3730C.pdf
Of course youd need a selector for these TV's but if u know what to do, these are hands down great tv's.
Sony Trinitron like the KV-32FS120 are great for older games too.
The reason why i am suggesting monitors is that they have RGB inputs for older consoles like the NES, SNES, genesis, N64, etc and have the possibility to be used in RGBHV for the best image possible.
