It isn't just the money, it's the time. I don't have my butt in a tractor seat long enough to warrant the purchase. And while I do like the fan, I don't want anything keeping me from hearing what the equipment is saying. No radio, no headphones, no earbuds.

Might need to be a mechanic to understand that last one though.

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
