DONT BUY THE CE!!!!!!!!!!!!!!!!!!! That's about all I know on the subject. One annoying thing about my FC 7000.... it's built like a tank all right, heavy and all metal. Unfortunately, the cutter assembly seems to like to loosen itself rather often. As in I have to partially disassemble the unit to release a couple screws, re-tighten and then I'm good... but only for about a month. Granted, the unit I have is a loaner from GRS in Pine Brook, NJ so it may have seen a hard life. Super accurate, easy to use and understand. Mine's a 54", the only 48" they make is the CE. Like night and day the two.
Short story long, get the 54" FC. It's not just a tank, it's a PANZER.
