If it's the mc-250 at AK in Barter town, then 800 seems reasonable without shipping.
It is absolutely mint and he lists the work done and who did it that indicates it is running fine.
So to the above post, it is in the 650 range for cosmetics and the 200-ish for the internal work done already.
It is a beauty and I love my mc-250, I may buy other amps, but I'll be hard pressed to sell mine.
