Haddon, where are you located that you are expecting pissy bees? (fill in your profile if you would to give us a clue :) )
All you really need is a veil and, if you desire, a long sleeved shirt. Veils are like $12 or so.
The tool you're referring to is a "multi tool" and can come in handy for sure, but I rarely use mine. I'd rather pull the siding off whole if possible.
$150 is a good start but if it's in a difficult spot you'll wish you quoted more!
