Newbie Question regarding ClickBank Video Game Beta Testing products

Hello everybody

I'm still pretty new to this IM stuff and I'm getting ready to start my third campaign. I'm bumming using Squidoo & Hubpages as my landing pages and I'm gathering traffic with Ezine and few other article directories. My first campaign has actually netted me four sales so far. My second has yet to convert but I am getting visitors. I was looking at getting a third going and was considering promoting a popular Clickbank product called Only 4 Gamers.

It is a subscription site that is supposed to help people learn and apply for video game beta testing jobs. The market is fairly saturated but I think I have found some keywords that I can bum with. I was wondering if anybody had promoted this product or another one like it? I searched for an honest review but got the usual it's the greatest thing since sliced bread stuff because the reviewer was looking for a commission.

I really want to try to offer quality content in my articles and was wondering how some of you veteran marketers get information for article writing when you know almost zero about the product itself. When I scour the web searching for honest info I usually find the same junk rehashed over and over. I REALLY don't want to buy this program. Is it considered nasty to buy a Clickbank program under your own affiliate code to get information about it then collect the refund?

Thanks for making this a nice place for newbies
