Thinking of getting a 12 frame used Dadant extractor. Its electric, supposedly works but "may need some cleaning inside". My dilemma is I only have 2 hives (A weak hive and a REALLY weak hive) with a plan to get at most 2 more. Seems like a big extractor for a small operation. The price is about half the cost of a new one but more than a brand new maxant smaller model. Has anyone used the 12 frame Dadant?? Pros cons??
