Why not just go the whole hog and post a link to your sale thread ?
To the OP - GLWS.
I think everyone can make their own system choice. I feel most are onto Arca because of the flexibility to manually mount lenses should you have enough rings, I am just saying a naked copal Digaron is the best starting point to go into a system where there's a very low supply of second hand. Ie it is the cheapest gateway. On top, being copal, it allows you to shoot film and here I am of the firm opinion that the Linhof backs are the best which extract most out of digital lenses due to their solid construction and planarity.
I had a few instances with uneven sharpness in the Arca system with Horseman backs. Never on a Linhof back. Alpa makes Linhof Alpa backs which is unique and a benefit if utmost quality is your wish.
Arca is easy in the sense you don't even need to send it to the factory if you already have a bit of parts lying around. Alpa on the other hand is thed most precise and has special bodies.
I own all systems, so I have a differentiated view on it - and yes, the Max IMHO is a good starting point as it also allows you to use the Linhof film backs.
I think it is a killer price for a copal Digaron, no matter which system you go for.
