Buying a used apexi vafc...

I am considering buying a friends apexi vafc and I wanted to know if it was ok..buying a used one.
He said it probably has no warranty.It has scratches from when he installed /uninstalled it under the radio in the
center console too.Its selling for $220 including shipping.
How does this sound or should I play it safe and get a brand new one?
Thanks
