Advise need on trainers
 

I want to get a trainer to carry on a yacht for a folding bike. At first i thought that trainers can only take 26"/700 wheel but then I have found that cycleops make an adapter to fit 20"/24" wheels ( http://www.cycle-ops.com/p-125-2024-wheel-adapter.aspx ). Now, i need advise on the type of trainer to get. Dont want to spend too much and want something that is realiable. In the cycleops range was thinking between the Mag or Wind. They are both $159 but which is better? ( http://www.cycle-ops.com/c-6-trainers.aspx?skinid=2 )
