I can't see why this would be a problem. I have seen many of Kevin's threads that have a cue and a price, also saying that it will be going to eBay starting Sunday. Why would there be a problem in giving both? Saying here is a price for this cue if purchased by x/xx, if not then it is going to the bay - that seems completely reasonable.
In my opinion, Kevin's threads are far less obtrusive than many of the ones that get bumped 10 times a day selling the same thing. I saw one yesterday that had been for sale at the same price for 11 months and had 3 pages of bumps...seriously, that's ok?
As far as the price goes, I completely agree. My earlier post was in reference to the "offer" posts. Having a price that is private because of the nature of the cue is understandable. The issue I have is when someone has a couple hundred dollar cue and wants offers. If you want offers, put it up on eBay and you will be forced into the best offer. If you want someone to purchase something, post a price. When I go to bestbuy, I don't ask the guy the price of a tv to hear him say, "well you can make us an offer on it".
