Have to agree with what's stated above. $100 would be my absolute max on either of those and I'd expect to lose money on the resale. They were once great freestyle machines, but the days of cartwheeling for hours are long gone.
I made the mistake of learning to kayak in a Pyranha S6. Made it hard to get into, but awesome once I got the hang of it. Knowing what I know now, I would have chosen something way more forgiving like an old Wavesport Diesel.
If you want to be the man, you've got to beat the man!
