I rode a Panasonic Team America from 1988 to about 1996, and recently refurbished it as a travel bike. It has Columbus SL tubing, beautiful lugs, crit-type geometry, and came with contemporary Dura-Ace stuff. It was a great bike, and I put about 25,000 good miles on it.
I recently had Bilenky 'hack' it, putting couplers in the frame and making it a travel bike. I built it back up with current Campy stuff, leaving the beautiful brakes (and the front der because I was cheap). They repainted the beautiful red/yellow/white fade paint.
I have to vote that Panasonic made some great bikes, if mine is representative.
