This 2001 year model USD- II is in excellent condition apart from the usual small marks and chips on the mount and legs. The mount has an autoguider port however the RS-232 port is only operable on the Temma go to models i.e. this is not the go to version but does have RA & DEC motors. Once polar aligned, the tracking is excellent as the PE is very low and can be autoguided if necessary. The SE-S tripod comes with Shimano quick leg releases. Cloudynights review here
