Thanks Bruce
Yep, I figured that at that price I was getting either the engine or the workshop at about the right price, and the other for free.
Seller didn't have many photos, but those he did have made both units look nearly new, and he did include a short video of the engine running the workshop, so it does actually work. I gave him my regular shipping advice, along with some extra for the workshop, like perhaps taking the drill press and line-shaft uprights off of the board and wrapping them separately.
In a BIN situation like this, one must decide yes or no and bite the bullet when the chance comes, as a good BIN deal often disappears within hours of being listed. Thought I'd take the chance on an offer to save a little bit on the shipping, so feel I did reasonable on the deal, depending on how it all is when it actually shows up.
