And that's fine. More power to you.

Most people I know have flat out stopped supporting the sx-20 just because they can't get parts, and when you do, they're used and sometimes questionable.

On the other hand, If you'd like an old sx-200 analog chassis with a full set of cards (condition unknown) and with intact power supply (condition unknown) I'll give it to for free... You come up and get it, and it's yours. No warranty, no promises, no gas money.

I will help you roll it out to your truck, though. PM if interested.
