I have the Brushless Compact Drill Driver...Model 2710-22CT...
Home Depot sells them for $199.00...
The biggest difference would be from Brushed to Brushless...I think...
The Fuel Series are great tools, with more power, a longer running time,, and a higher selling price...Larger batteries are included...
Professional Tool "Junquies" will love the Fuel Series, pay the extra money, and be ecstatic...The Home Based DIY'er, like most of us, not so much...
I looked at the Fuel Drill Driver, but, at $279.00, I couldn't justify it...
I am very happy with my Brushless Drill Driver...
But that is just one Old Man's opinion, and will, no doubt be challenged numerous times...
A lot of knowledge can be found by searching the tools you're interested in of the GJ...
