While there are good reasons to want a VGA solution, the best results with the least fiddling will always be converting 15kHz RGB to 15kHz YCrCb (component video). This is purely a real-time (no storage) analog (video opamps) solution. It has been published at least once, and should, with today's ICs, be both cheap and low-powered. I'm surprised that video gamers haven't made it more popular. -michael - NadaNet 3.1: http://home.comcast.net/~mjmahon
A commonly available solution thats popular with gamers DOES exist: <http://cgi.ebay.com/220698773448>
That same box is commonly sold worldwide as the Cypress CSY-2100.If you have a HDTV with HDMI, this box will work as well: <http://cgi.ebay.com/140531685637>
A good comparison of video upscalers (video game centric) can be found here: <http://retrogaming.hazard-city.de>
Keep in mind that the IIgs natively outputs what is called "240p" video on that page. I personally have a Micomsoft XRGB2+ and found that it works well with the IIgs. I also have several native 15.75khz RGB monitors as backup (including that SCART equipped Samsung LCD).
