If only one, get the 1400.
I have the 1400 and the 1010 (not the newest one, the laste generation), and I always us the 1010 for the LR-32 system.1400 works fine with the LR32 system as well, but 1010 is lighter, and when doing LOTS of cabinet sides it makes a difference.
The dust collection on the 1400 is just stupid awesome.
