I have a Kurt Kinetic, and it's an excellent trainer.

But first try a spinning class.

You can also look at other exercise machines.
I like my Concept 2 rower (the only brand to get) a lot
better than my trainer. And it's one heck of a workout.
I got mine used, it can take some searching, but you
can find one for about half retail, and usually they've been
used as a clothes rack. It takes a month or two to slowly
build up to the point where you're getting a good workout, and
most people just don't hang in there.

They are also upgradeable, and their new computer has some
cool chase games that I badly wish I had.

Just as a what the heck, try and find an Octane machine to try.
I like those, can't afford them.
