I just purchased a used Bilboa last week and took it out for a test paddle. In brief - I would recommend this kayak. It's great fun, stable, tracks well, handles nicely and sliced through choppy water.
The molded seat was comfortable but would be perfect with some extra cushioning. I had enough leg and storage space. As an extra bonus it also stayed pretty dry and has a wheel to make portage easy.
The only drawback - a minor one - was that this kayak is slightly cumbersome loading on to my car roof. I'm 5'10" and it was a bit of a challenge on my own but ok in the end. Besides that, the Bilboa performed great and I would highly recommend it.
