Hey hey, arguing about the zappers is fine but lets not bring the poor commodore 64 into this...mine still works, where as all my windows pcs have died after a few years.
But I have to say that I think you both have valid points:
Parazapper is trying to improve the technology so that it will help more people, faster and that is a very commendable goal.
getwisdom has seen the benefits of the zp zapper and is trying to make sure that people know that they can get results with an affordable product as well...also a very commendable goal.
You both should keep in mind that as the technology develops and becomes mass produced, zappers will become more effective and cheaper. So there is a good chance that a few years from now, its quite possible, that you will see zappers that are much more effective than the ones around now but that cost between $10 and $20. So lets just assist each other in trying to attain that goal. :)
