So Rich, never a desire to wipe them growth away has come to you?
I've been using a DE for 2+ years to shape my goatee without any problems.
Now if you're talking about trimming the goatee down in length so it does not get unruly, that's another matter. For that I use a hair (as in what a barber uses) trimmer with one of the comb attachments set to the length I want. The one I have has titanium (supposedly) blades that do not need to be oiled, and a vacuum built-in to catch the hair, but I've owned other models without these features and those are fine as well (if a bit more messy/annoying).
Best of luck.

You got a flo-bee?
I trim the outer edges of my goatee and square off the sideburns with a DE.
To shape up the rest of it, I use electric clippers with a #2 (1/4 inch) blade-guard to cut down the bulk of the whiskers, then I take the guard off to get the ends of my moustache and the areas to the side of my mouth.
The secret to using clippers is to trim whiskers AGAINST THE GRAIN, a technique that isn't immediately obvious ... it works out quite well.
