The ATF Chief 22 is really a very old machine. However, with you're budget of P80TK, it's difficult to find anything better. I suggest that you hire mechanic to have a look at the machine in order for you to determine its actual condition. Run a plate with a 16 x 21 flat screen and center and corner marks. Check the printed sheet for streaks. Run the printed sheets several times to check the registration. Check the screen with a magnifier to see if the dots print correctly or are elongated. Sometimes an old machine, if well maintained, can still print well.
Good luck!
