Welcome aboard, Eldredge - good to have another nutmegger on the site.
To answer your question, there's Kahn, in N. Franklin:

They seem to be fairly close to Willington. I have no personal experience with them, so can't comment on quality of service.
There's also Stanton, over my way:

Very friendly folks there. Helped me for almost an hour on a Saturday (they were actually closed) searching for a slip clutch friction disk for my tiller. Ended up not selling me anything for all his troubles. Seems like a straight shooter to me.
I am very happy with Ruwet-Sibley, where I got my
L3240:
Ruwet and Sibley - Home
But they are an hour West of me, over hill and dale.
Good luck, and keep us informed as you sort out what you will buy!
