if it doesnt include the impact, you should really specify... as its in the pic to the right of the skillsaw. that impact is the older generation... the newest one absolutely DESTROYS compared to the OG model.
this an excellant price, assuming all the batteries are good, and none of the tools put off that eletrical burning smell you get once the motors/brushes are toast.
xrp > LION, the lith ion stuff is lighter.... but does NOT last as long... i use dewalt 18v at work all day long... and NOBODY runs the LION stuff. the perfect compromise? half-stack 18v xrp batteries for stuff like the impact you keep on your toolbags...
