I have an old Performance Axiom variable resistence trainer that I'm no longer using and will give to the first person who wants it.  (Email me thru my envelope icon.)  The only problem with it is that the handlebar switch that controls the resistence is very stiff going from high resistence to low.  (Going from low to high is no problem, and you can manually release it back to low resistence at the flywheel.)  Otherwise it's in very good condition...and the price is right.  It's perfect for someone who wants to try using a trainer without having to make any investment.
