Bob,
How about quantifying the cutting speed more precisely? Before I
got my 7x, I used to cut up to 2" steel and 4" aluminum on the 4x.
Both of these could take 30 minutes or more. On the 7x, it takes
far less time for either of these (maybe 5 minutes), but that saw
cost twice what the DW872 does. Just curious, since if I wanted
add yet another saw to my collection my wife would have a fit. :-)
