I've been lurking here for a while and signed up to share this with you. I've been considering buying a used PF800 and today, I was perusing the amps at Musician's Friend over a cup of coffee and jumped all over this deal(PF800 Mint, Open Box, $329.97 with free shipping). I can't buy it used for that. I ordered mine and it looks like they have more, the link is still up as of 9:36am EST. Must be a mistake, new they are $599 and a blemished open box is $469. https://www.musiciansfriend.com/amp...eg-portaflex-pf800-800w-class-d-bass-amp-head Good luck and hope you can snag one too!
