Personally, I won't take this stone unless there is something that really captures me (which I think is highly unlikely). It may be the fire it produces or something, but in your case, it is definitely NOT the price. It seems cheap, but I would ask the vendor to provide me a few other options to choose again. If this vendor does not have, then look for another vendor for more options.
