Portable extractor fan

[Burdekin]

Could anyone please recommend a decent, reasonably priced portable extraction fan for welding?

Welding on the car down the end of the workshop and the fumes are lingering about. I wear a P3 disposable mask when welding and grinding but removing the fumes would be a good idea.

How cheap is cheap? I use one of these:

I pulled mine out of a skip, just needed the thermal fuse replacing but a new fan is only about £29 on eBay.

Thanks. Will have a gander on eBay as well. I haven't got a price in mind but don't want to spend too much. Younger sister announced two weeks ago she is getting married in Oz in Oct so have to fork out for us to get over for that so need to save my pennies.
