[size=14]I think the biggest factor for most users is will it work? I think $200 is very fair if the users had some indications of testing and some promising results.

Here's a possible suggestion. Take 1 or 2 people who would at least try the product for a month and post results. Of course they would need to be on the honor system and return the merchandise (or purchase) after the trial period. If they report that the product does at least deliver the cues and they have a way of verifying it, the product does what it's supposed to. It's up to the person to train themselves and see if they can get lucid from the cues.
