Interestingly, my two Kinesis keyboards were also purchased in 1999 and 2000 respectively. One is a Classic and the other is a Professional since the Advantage didn't exist yet.
Both keyboards are still going strong with very heavy usage. Like you, one of mine drank som soda several years ago. I disassembled it, cleaned it as well as I could, and reassembled it and it's still doing great to this day.
People look at me funny when the see the AT connector on the keyboard attached to a PS/2 adapter, attached to a USB adapter but I wouldn't trade my Kinesis keyboard for anything at this point.
