Go to Predator's website, I believe they list the MSRP for all the cues...look under Retired Cues, find the one you're looking for, knock 20% off the MSRP and you'll know what you would've paid from most retailers.
Depending on the asking price and the condition of the cue... Should you not be interested in the cue please PM me w/ the info. I may be interested. If the deal and cue are right I am sure a finders fee would find it's way to you also. The better the deal, the better fee. Should you have a really good oppourtunity to purchase extremly low... profit is not a dirty word... All I ask is that you are honest enough to not mark up the cue and collect the finders fee. Thank you for your time.
