Im not sure wether you mean well or your just plugging that link again,its a pointless thread either way.
I doubt anyone has a problem with buying second hand machinery,if its made for the job, the space is there and within budget.
This is mostly a diy forum where a lot are of the mind of why buy when you can build it,
Others will build out of necessity because they cant afford to buy and even then most budgets seem to fall below £2000.
most logs seem to be wood router style machines(moving gantrys) and used mill conversion logs .
