Agree with both sides.
I agree with both sides, potential seller and buyer respectively, and can certainly relate to the OP that even a ballbark, "asking range" with a "B/O" or MSRP would be great.
I personally, have honestly skipped over some really gorgeous cues and interesting posts, later to find out it was definitely in my price range or at the least, gather the add'tl cash or other, if it was something I couldn't pass up on.
It's easier for a buyer to see a picture of something they like and take action than to post a dollar amount out there and play PM or thread tag to see if something could interest them plus be in their price range.
I don't know. Like my title says, I "agree with both sides" and a shoutout to this post and kudos to Duc, who has a great seller rep., and is very communicative, I've learned.
