picked up 3 more today, Sharp arm 277 copiers. These were a heck of a lot heavier than the last ones and they were on their own 'C' shaped frame. There's like - 4 different sections to these babies. these are also more expensive to buy new than the first 2 I got last week. Just spent the last 4 hours tearing the first one down, taking longer than last weeks what with being more to them and all. had to come in and warm up!
