Low speed option depends from fan, so only difference would be to buy bit different fan.
Fibre work is something I'm staying bit away, though. Never had done such a job. But electric fan is on my todo list

Volvo 343DL vario -81 -running-

Volvo 240 Diesel -83 -undecided-
Citroen ZX Dturbo -97 -daily-

What kind of shape is your radiator in? I was shocked at the difference it made to my car...and at first sight it wasn't that bad... I got a genuine Volvo one from an independant specialist for ~£87 (ie: about half price!)
I know almost all Volvo electric fans are two speed. I'd try pulling an e-fan from something as new as you can find - say an 850, or a '70'. You'll then need a controller. The aftermarket ones seem to be quite expensive for what they are though. You might be able to hook up the control circuit from the donor car.
I'm going for a blower (ie: in front of the radiator), since they're supposed to be more efficient, but you're now talking me into a two-speed arrangement, as I don't really want it making a racket whenever I hit the AC button...
Speaking to Ravennexus last night, he said most German manufacturers use electric solenoid couplings...ie: full lock-up and total disengagement. A later development of our mechanical couplings. Worth investigating maybe? I might look into it myself.

My rad is fine, because I replaced it a few months ago. The old one was cooling fine too, but it was starting to get a bit rusty, and because I needed the one with the extra hole on the bottom drivers side, the part was a rare one. Apparently it had already gone unavailable but they happened to have one sitting in the store in Daventry.
Interesting idea to get one from an 850/940 or something.
EDIT: also, don't go for a blower, you should go for a sucker, as they're by far the superior. Blowers block the airflow when they're not running and when they are running, air escapes round the side.

This is what 'everyone' seems to say, but it's not the advice from the fan manufacturers...and I'm sure the majority of serious performance cars have blowers for a good reason. Having said that, if I want a rad, IC and a condensor up there, the decision might be made for me...
