At the last Texel there where a few "exotic" 20-footers which could be considered affordable.

There is the Czech built F20-Predator which goes for €25K ready to sail
We were sailing behind one on friday and dont think I have seen a cat pitchpole that hard for a long time!

There was also the Polish built Exploder which has been competing at Texel for a few years, not sure how much it costs but since their F18 goes for €11K it cant be as much as an M20 or similar.
