Before I give my opinion on how the OP should proceeds, I want to comment about whether to pay for a cue before its made.
Peanut1pool said there is nothing wrong with paying up front with a reputable cue maker. If someone takes Peanut1pool's suggestion and subsequently gets burned, is Peanut1pool liable? Who is a reputable cue maker? Is my list the same as Peanut1pool? Will Peanut1pool provide us with a list of reputable cue makers that other members can pay up front? And, if a member does pay up front and subsequently gets burned, (to quote from the movie Rounders) its on Peanut1pool!
I see so many times where a member will vouch for a new member or a member with limited reputation. However, I'm not sure people fully appreciate what it really means to vouch for someone else. I think its like a personal guaranty.
Now, I'm not going to suggest or recommend members pay for a cue up front or not, that's each individual's decision. That's the beautiful thing about living in the US of America, you have the freedom of choice. And, to me freedom mean you have the right to screw up. But, if you pay for a cue up front and get burned, then don't come on here complaining, you get no sympathy, at least from me. It was a valuable lesson, expensive, but valuable.
Now, how the OP should proceed. Seek out advice from an attorney. Don't rely on advice from a bunch of pool players. Many times I see where a member will comment about reporting to local authorities, which fine. But, I believe that would result (if you're lucky) in a criminal charge. I'm not an attorney, but I don't think criminal charges will get your money back. Again, seek out advice from an attorney. However, I think at $850 you could take them to small claims court (I don't believe you need an attorney for small claims court). I have represented a bank many, many times in small claims court. If you receive a judgment in small claims court, then you can garnish wages or possible file liens on assets. I'm going to say this one more time, seek out advice from an attorney.
I agree with Measureman, it is your responsibility to protect yourself.
As far as, list the name of the cue maker, my suggestion is don't do that. There could possible be some personal liability. Again, it's your responsibility to protect yourself. Others would be more than happy for you to liable yourself while protecting them (so they don't buy from the person you listed).
Respectfully,
Steven
