The VZ2500 I sold - the sale fell through... After It sold for that incredible amount, I went back and decided to give it a very rigorous testing before shipping. That was when the damn gear in it cracked- right before my eyes! I was glad it happened before I shipped it at least- But after immediately telling the buyer I would have to pin the gear, he was ok with that, then next day got cold feet and cancelled the sale.... sigh...... so anyway..... live & learn..
