Rod,
On the contrary, it shows clearly how HWE massively outsells dry compound systems.
The reason there are so many secondhand wet systems for sale is that, as you well know, a large proportion of new business start ups in the industry fail, due to lack of proper investment, and an inability to get the business in quickly enough before they starve. Hence another half price 'nearly new' machine for sale.
That's all I'm going to say on the subject.
I'll leave any final petty point scoring comments to you!!
