a scan line generator from crafty mech
Here's another scanline generator.
It's a Dreamcast VGA box with scanline features, but the connection cable can be interchanged with a VGA cable, allowing it to function as a scanline generator for any VGA input source.

It's $60 which includes shipping, add an extra $5 if you want BOTH of the Dreamcast and VGA connection cables.
But this box has a few nifty extra features, selectable via 4 switches :
>> Scanline On/Off switch.
>> "Even" or "Odd" scanlines.
>> Scanline width selection ... "Single" or "Double" width scanlines.
>> There's a 4th switch (intended for the Dreamcast VGA box functionality) to toggle between RGB video (15khz 480i ), and VGA video (31khz 480p).
