On the other hand, their site looks extremely scammy. They have a gigantic page for their full product, crammed with testimonials and claims of how much you can save, but the price you actually have to pay isn't anywhere in sight.
I usually never buy products like that because in most cases I could recreate it myself in ruby in a few hours, and to be honest that was my intention initially.
However I was impressed about the overall quality of the product and decided to buy.
They also have a series of videos that were very useful to me in case you are interested: http://www.noblesamurai.com/dojo/marketsamurai/
E.g. the famous art gallery scam is what sells art near tourist attractions, to judge by how often it pops up.
