Where to get a cheap window motor for an 80 cabriolet

[Vince70]

I'm having a bit of trouble sourcing a new/secondhand front drivers window motor for my 1993 Audi Cabriolet and just wondered if anyone knows whereabouts I could source a cheap one from.

First of all I thought it must of been the OMG audi electric window relay problem but I tried another relay and the window is still as dead as a dodo and can hear a nice healthy click from the relay so I imagine it's ok.

Also I just wondered is it possible that there is another window motor from the VAG range that will fit if there's one that would be easier to source.

Thanks
