I am not a contractor, but a homeowner who is building my own house. The DW708 is an excellent tool when it is new; however, over a short period of time, with inconsistent use, the slides get loose and does not cut an accurate angle. You must keep the locking screw snug which is not the way it is supposed to operate in that it is then difficult to slide without this screw being loose. It also has no dust protection in the table bearings and eventually becomes difficult to move the table from one angle to another. Again, I do not use the saw everyday so I am confident that anyone who depends on this tool daily to give them accurate angles would be disappointed after a short time.
