I have talked to over the phone twice and you have told me that you do not have a shop per say but more less area whole seller. Nothing is wrong with that as long as the product is correct and the warranty comes with it. I live 20 minutes from your phone# and have spoken to you twice. No problem, except you want show me your product. So, there is a situation, you don't have the product, 2nd hand product producer. That is fine as long as there is a warranty that comes with it. I have looked over all the products and parts that come with it except a few I would have added. But, being the field, tha'ts my choice and sumother also's. Now like the pressure guages, intakes, VFD's,,, that is a totally different story. You are discussing a nother science. I would be able to discuss this in another cup of coffee with my buddy from Red Eye whom lives 15 minutes away. We could learn alot from each other and no el problem from that. Luv to learn.
