Hi - first post alert so please be patient!!
I would like to purchase a pre owned NZ and a couple of questions have popped into my mind whilst searching.
Is there anything different between the early/first generation NZ that I should look out for and where there any improvements in the more recent models?
Also, (I know it’s ‘how long is a ball of string’ question depending how much use it’s had!) but should I be concerned about the burrs being worn out as a brief search shows that should they need to be replaced they appear to be a large chunk of the purchase price. Obviously, if the burr wear is an issue that might push me into buying a new one.
Many thanks. Jules
