Thanks for the input guys but the reality around here is that there's a very limited selection.
You Americans have a wider range of cats available.

As I said, I have never even seen a cat out in the water around here and I do alot of motorboating and fishing in the archipelago waters.
In midle Europe you can find more cats but here in Scandinavia they are not that common and I think the only brand available is Hobie.
(One cat dealer in the whole country as I understand it and they sell Hobie)
Perhaps there's a few Tornados as earlier suggested, but I doubt that anyone will know what I talk about if I mention Prindle or Nacra.

I'd think my best chances of ever getting a reasonably cheap cat is to find a used Hobie 16 or buy a new Wave.
