Where can I find a hex inverter?

I am looking for an everyday electronic device that I could rob a hex inverter out of. Like a 74ahc04. Not that I am cheap, just wanted to say that I made this project without needing to goto the store and buy parts. Mouse? Old Printer? Old Scanner?


Thanks

...or an old computer, photocopier, check them all you never know where they could turn up.

I found one

I found on in an old DSS Satalite Receiver. Thanks RCA!!!!!
