I'm interested in your 589 but to be honest not for that price. when buying a used laser the buyer is taking a risk. I have no idea how much run time is actually on it, how you cared for your lasers, followed suggested duty cycle ext. so for me the risks don't outweigh saving only 20$. I would rather buy new.
I not saying you are lying, or treated your lasers poorly. This isn't personal it's just how,it is. A buyer needs to approach any transaction with these risks in mind so don't take my words as attacking you.
I have bought 2 used lasers that were not what they were said to be so since then I am more careful and the cost savings has to be significant enough to take the chance. I'll keep an eye out on this thread but I'd say the fact that nobody has bought the 589 in these many weeks to me shows your firm asking price may be not very attractive to buyers. as yellow is a very popular wl at the moment. These usually sell in days if not hours,
