first product ppc tests - Samurai or Keyword Elite 2

I have a product that I want to generate sales for with PPC to split test and increase conversions.

I'm going to be testing on Yahoo and MSN at first so as not to have to mess with google and the whole quality score for right now.

I'm creating my first initial PPC keyword list, would I be better off using Market Samurai or Keyword elite 2 to start off with?

thanks

Well, most of them are really good at gathering results for G. But, msn and yahoo traffic are so unstable and they don't have a high quality traffic as g has.

Another thing i realized is, some products are only profitable on one search engine. That's either because the competiton is fierce on the other network so it is not profitable under those per click costs, or the traffic just doesn't convert enough to become profitable.

I had one campaign that i promoted on three search engines. I tested it for about a month to see if i could make some money or not. Same landing page, same ad copy and adwords campaign was profitable after a few tweaks. But other ones failed miserably.

Ke2 is $197 but i saw a $50 discount code somehwere here so both of them have almost the same price. I can definitely say that they are excellent products and you can't go wrong with any of them. I'm using ke2 because of the time machine and the cpa magnet functions.
