One problem with theese rigs is the digital PCB board. The soilder joints are bad. When it gets warm, the contacts may open and you can get all sorts of funny displays. You can also find some functions not working.
I would check it with a good magnifying glass and go over the soilder points with a soldering iron. You remove the eight screws on the sides, remove the top and bottom cover. Move the front panel, and you can fold back the PCB board.
I think it's a nice rig to operate. Light and compact. If the maintainance mentioned above is performed, you should be all right.
