I have a 900 in my shop/office/garage because of the charger base! I have the 900 mounted on an 'arm' from the left side of my desk. The charger base would have looked stupid connected to the 3/8" square tube mount I made. I also need the display to be on at all times since I don't pick it up. The 950 display comes on with a button press but that isn't what I wanted.

I'm glad they make a variety.

Pick the one that works best in you situation. I'm happy with both!
