Interesting……. I wish the author added pics of the chambers he was referring to in his article instead of having the Sechrist 2500 photo with MJ in it. Anything for attention to the story I guess. FYI – a Sechrist 2500 chamber is around 1500 to 1700 lbs (That’s not considered portable!). Using that photo in your article is like selling a Honda on ebay with a photo of a Rolls Royce genius!
