Okay okay, I'm liking the sound of this Electric fan more and more, though it does seem to be a bit pricier in the short term.

Anybody have any suggestions on models that perform well and would fit? Looks like the the slimline and flexalite fans get good reviews and seem relatively easy to mount?

Side note: Since the electric fans push more air around, can you go with a smaller diameter fan than you would otherwise? Or should one go for the largest diameter that will fit?
