[Wear-Hard] VGA to NTSC conversion

[Justin Shands]

Okay, so I have some Spy Car replacement HMDs on their way to me, and
I'm trying to finally get my Wearable off the ground. I have a
Twiddler 2 and an OQO01, all I need now is a converter for VGA to NTSC
to use the Spy Car viewers(after I hack them to NTSC mode instead of
PAL).

What is the recommended product for this? I know Steve Mann used the
AI Tech "Pocket Scan Converter" in his WearComp6 project. Is there a
better solution to this conversion? I checked their site and they
don't seem to be selling the Pocket Scan Converter any longer, just
replacement power supplies...

Do they have an equivalent product(in terms of quality) available in
their current line? http://www.aitech.com/products/converter.htm

Are there any more recent products that perform this function better/cheaper?
