We had an Exposcop 7000 in fellowship. It was reliable, very fast, well balanced and easy to position as Ligament has described. Very nice if you position the C-arm yourself.
Image quality was far inferior to the newer hirez machines though. I think that 7000 was ~ 500 lines analog. A side by side comparison with a GE 9900 was striking.
The same machine with 1k digital rez would be great.
