Help ! Looking to buy a Mono ski ( for snow not water )

[Por911T]

As it says Im looking to buy ( new or 2nd hand ) a mono ski - it was a big 80's and early 90's craze on the slopes , but today they are virtually extinct . Please note Im not looking for a snow board its a mono ski ( ie one big fat ski ).

Any input / ideas are appreciated .

Thanks
