That sure is a nice building that EH has(had) in Belle Plaine. I used to drive by it just about everyday on my way to work. Makes you kinda wonder why they died so soon. I would think that a building like that is a bit overkill for a fledgling company. I would think that you would want to prove your product, make some money, and then build a kick @$$ building. I'm rambling again, damnit, my point being that is one hell of a nice building in Belle Plaine.
I love it when a company that relies on an OEM's R&D (outdated though it is) that is combined with aftermarket companies' additions and then has the gall to tout its own research when promoting their product.
I hope you at least save some money from ordering all the parts yourself. Still, you don't have the pleasure of perusing the catalogs during your R&D.
