I have a used HM330 which has been working well for past several years.
Recently, the quick release clamp does not lock the knife/holder down well,
which is causing problems in knife consumption and quality of sections. I paid
~$3000 about 4 years ago for this one. Does anyone know whether
I have put up a spare microtome on ebay if anyone is interested there are
three days yet to bid on it. It is in perfect shape and includes the block
holder and disposable knife holder.This microtome is well made. I have
four of the that are in use everyday and we never have any
