I use the Milwaukee Pro Vac. It looks and sounds Professional. I carry it and dropcloths into the house first thing on arrival. It makes a better impression than 50' of extension cord and 6' drill bits. :)
The job isn't finished until any mess is cleaned up.
I believe it is private labeled for Milwaukee by ShopVac.
Experience is what you get when you don't get what you want. Any wire cut to length will be too short. I must be a near GENIUS. All my teachers told me I was at the very PEAK of the bell curve!
