When you think about buying an extractor, think about where will i be with my bees in 10 years time.
A good extractor should last for decades.
First extractor i bought was a 2 frame hand crank, caught the bee keeping virus and in 3 years later bought a 78 electric. We ahd 42 hives then but new i was heading upwards in numbers. Never looked back.
A rule of bee keeping purchasing is think what you need and double it. Whether it is frames, boxes, timber etc.
