I'm sure the both of you will have a Life-Long list of dedicated Customers!!
Any chance that your shop could represent Kleemann (compressor's)in Denmark as an Authorized Distributor/Outlet? If you follow the Hotrod Forum, I'm sure you realize the demand in the US for a solid product that doesn't compromize longevity and that does not a require a second morgage on the house! (Not sure what they might cost?)
Just a (wishful) thought, I would wish you both luck, but you don't need it!
