Used is fine. That is what I have. There is a guy locally who makes trikes using these cars and he has a little mini Saab junk yard full of front ends. I just went out and pulled the unit out of one for around $80. I have no clue if that was a good price or not, but it worked for me. They are in a well protected area so are usually fine and don't for get to pull the transmissions from the cowel as well. If the tubing that the cable runs in looks rusted, no worries it is just 5/16 brake line with standard flares on them to fit into the drive and transmissions. Do get the tubing though because you will need the flare nuts.
If you just want new, I suppose you'll have to order it from a dealer or check with some of the guys in Europe. Or, just buy the new unit from the guys in Georgia that I provided. It works the same way.

If you want to have fun, find an older Saab 900 and take the wiper system out of it. The one above is a sort-of copy of this Lucas system. Like the ones in English cars, it uses a drive cable in a 5/16 steel brake tube and NO external moving parts. You cut and flare the tubing and clamp on a transmission where ever you want the wiper. The BIG difference is that it has knurls (for attaching the arm or arms) that is the size of standard American arms (not those little bittie things like MGs etc) and it has a much wider 165 degree sweep. They are sweet. Enzo at Finish Line/Moto-Lita America can sell you a switch or I can show you how to implement the park feature with two toggles.
