Does anyone know were I can purchase a probox checked everywhere online and nothing

You can order them from munkustrap here on this forum. There's a separate ProBox forum section on the main page, where he posts more frequently. Such as in the following thread:

viewtopic.php?f=7&t=1646&start=40

He shared a link there, where you can contact him to ask question and order the ProBox:

His direct e-mail is also mentioned somewhere on that thread, but without the @ symbol, so web crawlers can't pick it up and spam him. I'm sure you'll find it... his name is Ralph

...and the ProBox is awesome!
