I agree that listing a cue for sale without a price is not the best way to actually sell it. It's rarely successful for the poster.
For that matter, I just ignore the listing regardless of what my interest in the cue was or might have been.
Listing it here is really a virtual classified ad, it's not an auction or blind offer system. Prices, specs, pics, etc., are needed to sell something.
The exception is when a known (read: great rep) seller has a product for sale and they want to move it quickly - regardless of price. For example, JW Petree listed one of his conversion cues, "to the highest bidder by x-time". But this was a new cue that he built, and his reputation is flawless. And whether it went for $200.00 or $400.00 was OK with him, not this "if I get a magic number I'll sell it" crap.
But the Posters that think they're going to get offers of $1200.00 for a cue that sells for $850.00 in the secondary market are just wasting everyone's time.
They have the right to post, I suppose, as we have the right to ignore it. But it's nonetheless a futile exercise on their part.
Just my .02c
