Great purchase if below 13 dollars. I was glad when the price went down from stupidity to reasonable. The product is very well done and should see a larger fan base with the reduced price. If you market off of production cost your playing it safe but more likely to get kicked in the balls on any PDFs over 15 base and there's was 20. Do the math it's a no brainer.
"Bottom line only purchase when on sale or if money is not an issue."
