Hi Steve,
I'd say it's best to test your click-throughs using either of the methods. Having the price handy helps the reader get comfortable with you and if you publish the price in easy understandable numbers, eg, x amount per day, etc, interested prospects carry on reading.
Customers are customers only because they are interested in your product or service and the results you promise. When they are prospects they evaluate the product/service using many factors and price is a major one. If the price is kept hidden it creates irritation to buyers and they may find their own answers as to why the price isn't shown.
As long as the price and the perceived value of the product/service are in cohesion, I won't mind reading good copy and interesting points. It has to be useful to me and to my business.
Just a few comments.
