Bio-spot or Advantage

[candy722]

Ok, Im now trying to potty train my dog to go potty outside instead of using wee wee pads inside my home. I've never used bio-spot or advantage. From what I heard is Bio-spot is suppose to be really good and affordable. I know everyone uses advantage but it's really expensive. I know some people that also use frontline. I know it's alittle cheaper than advantage but bottom line what is good and cheap. I got this flea chart from dr. foster and smith and bio-spot is suppose to be better which im happy because it's only $6 compared to $40.00. http://www.drsfostersmith.com/pic/article.cfm?dept_id=0&siteid=12&acatid=176&aid=281
Any suggestions of what's better?

I just saw an ad on advantage that's cheaper than everywhere that I found. And the difference is that it's from Australia. And they say that there is a slight difference between advantage from US and Australia. I got it from the banner that was flashing on this web forum.
