I know March is historically slow for trees in the northern us but wondering if January and February were slow for some and right when its supposed to get busy this happens? I'm glad I have no payments to make.
Personally I don't think there's enough of a difference to justify an in betweener for those 2 saws. I used to keep one in that range but always grabbed the 440 anyways.

Usually eab is in an area at least 3 years before an arbortionist gets lucky and finds it. If it ain't there yet it will be soon. I know you're the only fine pruner in town so it sounds like it's up to you to keep your eyes peeled for the little devil!
