The title says it. I am trying to find a cheap bottom coil that I can buy in bulk and get replacement heads for it. I will need 20-50 of them. I am a top coil person and don't know much about bottom coil. Just trying to help a friend for their B&M. They want to stop using disposable top coil and go to cleanable and head replaceable bottom coils for the testers. Thanks
