Hi Alan,
That's a great question and as suggested split testing is the way to go.
Without looking at the actual product itself its hard to determine what you should be charging for it.
One way is to simply look at what other people are charging for similar products. If your competitors are charging $97 then don't sell yourself sort. However, test it out and see what difference it makes to your bottom line.
I'm in the process of doing something similar with a membership site, currently in pre-launch as a WSO, for which I charged $17 per month. I've almost got 50 people signed up now, and I'm going to push the price up to $27 for the WSO. I'm hoping to eventually launch the product at the end of the month aiming at the $47 per month price point. But without testing it's difficult to determine if the $47 price if going to be a bridge to far.
