I am trying to financially control my purchases for my watch repair hobby addiction. I see on ebay where there are demagnetizers that go for $10 and there are others that go for $600 or more. I know, based on my research, that for tools like tweezers I should buy the best because if not, I will be frustrated when I sling a screw across the room, etc etc. Same is true for screwdrivers. I know you should always purchase the best you can afford but I am not sure that spending $300 on a demagnetizer is a wise expenditure. Your comments are truly appreciated.
