So I need a Pit Viper 10cfm fan, but for the life of me, can't figure out why they are so much money! I mean, $68 for the fan + another $15 for the mount? I'm at $100 after shipping just for a packaged up silly fan and mount. Kind of burns me, if you can't tell. I'll pay for the electronics, but the fan unit are just dumb, non-complicated mechanics.
