Mission 774, one of the best?

I friend of mine has this table and to be quite honest, it is quite amazing to say the least. Not that I have heard as many tables as some but whomever designed it put some serious thought into it. The tonearm that is on his table was the tonearm that preceeded the Mechanic. I do not know how much these tables went for initially but I have never seen one come up for sale. The only downfall with a table like this is where would one find parts? Has anyone else heard this table and if so, what are your thoughts on it?
