Same as if it has a worn out playfield from playing the crap out of it at home. HUO is meaningless.

I have a lot of crap that is worn out in my home, and it is all HUO.

I paid $900 for mine. I liked that it had no mylar, no missing plastics and untouched electronics and wiring. The major items I had to do were to rebuild the light grid and repair the cracked spiral vortex. Can't wait to sell it for this price. (jk...not for sale!)

In some cases sales ads can be misleading intentionally, pumped up to push a sale, but then there are those that are 'somewhat' in the know, not intentional - but just not in touch with the pinball hobby community. Maybe not maliciously trying to mislead. And still other items are subjective to interpretation and personal value. Not only can a machine be said to have a monetary value, but so can individual parts and condition...what is worth something to you or me or someone else is subject to interpretation. I consider untouched boards without hacks or battery leakage corrosion to contain more value to me than something that has been previously worked on, for example. For my Pinbot, the vortex was cracked but I actually missed it in the pics I was sent in email. I figured I would repair or replace that at some time. I drove 4 hours one way to see it in person, and while the broken vortex was mildly disappointing, it was going to take a lot more than that to be wrong with it for me to drive away without the Pinbot.

I don't think it is wrong to point out your discrepancies with a games condition or price when you see an ad, no matter where you see it for sale: Ebay, CL or even on Pinside. As long as you are polite about it, and voice your opinions why with detail, I think it benefits both buyers and sellers in the end - for those that care to think about it and evaluate it as a part of the sale. There are those who will refuse to listen, and that is their perogative, but sometimes constructive criticism can help both parties to a comfortable conclusion.
