We've got a mobile Sherrill/Vermeer dealer, Jerry Rouse, who will, more times than not, show up at our jobsite when we need something (anything, actually) in a pinch. Sometimes he'll come from several towns away. Also, he comes to our yard every other Thursday. He has half their catalogue right on the truck. He special orders stuff that Sherrill doesn't list, as well. Does research for us, looks into new products, explains and demonstrates gear, sponsors many local events, then feeds us during them!
And yeah, I occasionally find an item at lower price over at Kuemmerling or other, but usually not, and sometimes it's the other way around. Try asking a Kuemmerling rep about Cobra, or belaying devices! Saves me alot of time, and takes some of the guesswork out of purchasing, since we can check out stuff live, and even demo it. He replaced 2 consecutive poison ivy 150 ft. ropes with bad splices, no questions asked.
So, we don't even price shop much at all. I would't want to be less loyal to him than he's been to us.
Jerry, this one's for you!
