Help. I'm melting.

So far the only drawback of quitting my job is that it is HOT here! We don't have AC like we did at my office. (Where someone would always turn it down to 58 degrees and I'd end up wearing a sweater and socks with my skirt all day.)
In general, the house stays really nice until around 1pm, when even the slightest exertion (like typing) or embarrassment (the mailman hearing me sing to the girls about diaper wedgies) can make me break out into a sweat that doesn't go away until about 3am.

So please help. I need a ceiling fan for the living room. Should I:
a)
buck up and buy the modern fan "ball" one? ~$275

b)
get a cheapo industrial one that is sure to cut off a finger? $70
(Actually, this is not even an option because it literally WILL chop off a finger. They are only recommended to be installed in tall ceiling spaces. Our ceiling is only about 8'-6" max.)
