I have a lightly used Alpacka Classic model size small (alpaca) in wonderful rubber ducky yellow for sale. Comes with the usual seat, inflation bag, waterproof repair kit, and a storage bag (storage bag has a slight tear in it but is still functional).
Used a handful of times, mainly in the desert SW (Escalante, Colorado, etc..) and well cared for, in very good condition.
Forgot to mention this included the shipping cost which is like $60-70
