I already have the PE14. I wouldn't buy the PE8 simply because it has a rocker switch and not a traditional rotary variable speed trigger. Great tool I'm sure, but I simply can't understand why they went the route they did. For delicate and intricate work I feel it's a must.
Exactly why they made it, for intricate work. Your right about that cumbersome switch. I still favor the Mini for work that can be done with a 3.5" pad.
