Has anyone used older consoles with the newer Sony LCDs?
Yes, you will see lag on the older consoles. Whether or not it will be enough to bother you, I don't know. These models do have a Game Mode IIRC but as you know no Game Mode eliminates the lag 100%.
With an iScan VP50 (or VP20/30 w/ABT102D) you could fix the lag problem, but you might introduce some deinterlacing artifacts on some of your Sega Saturn games.
I know that the Sega Saturn can output 352 x 240p, 640 x 240p, and 704 x 480i. The games that output in 480i would be fine, but apparently, the iScan VPXX models can't properly handle a 240p source (they're treated as if they were 480i) and you'll get some ugly motion artifacts in exchange for stopping the lag. To be fair, though, most HDTV scalers don't know what to do with a 240p signal either--any games outputting 240p are probably going to look ugly either way.
For 240p-only games and consoles, I highly recommend the XRGB-2+. Although difficult to find, this box handles 240p signals quite well and can output 640x480 via VGA out (and you could let the XBR3 do the scaling). Alternately, you could get some cables to adapt the VGA signal and try inputting it to an iScan VPXX but that's probably unnecessary.
PSX output is strictly 480i, so you wouldn't have a problem using that with an iScan VPXX.
The XBR won't "stretch" the 4:3 image to 16:9 when you're just playing it hooked up straight to the inputs; 16:9 is only forced on HD sources.
If you're going through an iScan VPXX (and outputting 1080p, for example) the iScan will have an option to output the game in a 4:3 windowed area of the 16:9 output, so your TV will still be getting 16:9 but your old games will not be stretched or distorted.
