Susan, here's the picture of the galley fan complete with grease. The fan works really well and the light ends up in just right place too. Downside is that we probably restict passive air flow a bit, but we are happy to make the trade. It's pretty low power consumption as well.

Thanks...your link leads me to a British site...Is this where you purchased?
Sorry about that. I thought the manufacturer's link would be more useful than my local Canadian retailer. Didn't realize they were in the UK.
I bought it at Steveston Marine:
