I went to your profile it does not give information as to where your stihl /echo chippers storefront is.
here are some interesting stuff from that profile.

You might look up member 166 here he seems to have a Dolmar dealership that sells echo chippers.
Have you tried to get another chipper manufacturer to come to your open house? one that you do not currently carry and has a model that you think might be of benefit to your customers?
Here is some more stuff from your posts in this thread
How to convince, coerce, jedi mind trick, blackmail my Echo rep....
We sell some of the Bearcat line chippers and splitters , no saws since none of the professional outfits would be interested.
To me it seems you are not willing to enter into a contract to sell the entire Echo chainsaw string trimmer etc line. I have no idea what your contract with Stihl is. I thought it odd that Husqvarna Echo, Dolmar, and Oregon with their cordless electric had test it out at the Paul Bunyan show but Stihl stuck with putting on the timbersports and the Stihl dealer association seemed to be hosting carving. Go to a forestry show and test out the echo stuff if that is possible. Kind of sounds like a trap or just trying to get them to come as an advertising ploy for your open house.
