Hi, Mountainsong; the replies you get aren't necessarily going to reflect the overall opinions on buying new or used. It's a limited sample of people that are willing to take the time to reply. But you probably already knew that.
The question you should ask yourself is: Am I willing to take a chance on buying used in order to get a cartridge that I couldn't afford otherwise? And, if the used cartridge shows up damaged, am I willing to then have to spend even more money to either repair it or buy another cartridge? (Some sellers will allow you to return the cartridge, but then theyre at risk because you might have damaged the cartridge.)
Its a gamble, and you have to be willing to accept the outcome if you lose. I tried buying used cartridges twice and both times they were damaged. I was able to return one and got stuck with the other. So I didnt save any money and actually spent more money than if Id just purchased a new cartridge in the first place. I wont ever buy a used cartridge again unless I know and trust the seller. And I want a money-back guarantee that the cartridge is in the stated condition.
Good luck if you buy used. :-)
Regards,
Tom
