Rowing machine which can be folded up ?

[FeelingLucky]

DH wants to buy a rowing machine. He says we can get one which will fold up and fit neatly in a corner when not in use.
Anyone have a recommendation?
They seem awfully expensive.

The Concept 2 dismantles into 2 pieces but I wouldn't say it neatly fits in a corner of a room. It still fairly cumbersome. Must admit, not looked at other types though.

Thanks, will look that one up.
Anyone else?
