it makes no sense to buy it when it can be made for pennies on the dollar. i make it with my own setup. but even buying the more expensive makers will be paid for in a matter of weeks. where else can you get that kind of return on investment? visit the CS forum here and see steve555's posts. he has posted a link for a maker for $25. the better ones are 100-150. the silverpuppy is recommended as one of the best units, as well as silvergen.
