Ernie,
The 'guy' answering the cell phone is the owner, Steve. I have talked to him many, many times over the past 3 years, oftentimes when he was on the road, once when he was on vacation. And when he did not answer, he called back in one day, or in a couple of hours. His business is more of a mom&pop business, with a small staff, and that helps hold down costs which is to the benefit of the customer. Customer service is generally for service after the sale for the customer, but can be accessed prior to a sale to answer any questions prior to a sale not covered on the web site. Between his site, and the forum, there isn't anything missing on the SI line of smokers, unless one is looking for flashy videos and eye candy. And those can be found on youtube.
Good luck with which ever company you go with.
Dave
