Do you want SUGGESTIONS or CHOICES?

Put yourself in the shoes of a consumer for a second to help me out. I'm in the midst of making a site that will be using Commission Junction but I just can't decide how to model my site:

I could put up pages each reviewing 1 single product (in a suggestion-like fashion) OR I could put up pages that just list 20 different similar brands of an item (EG: Pretend my niche was running shoe...I could list 1 running shoe and suggest it w/ features and stuff or I could list 20 different prototypes and manufacturers with small 1 sentence descriptions).

What would you want? Just the suggestion (maybe with an advertisement at the bottom of the suggestion saying: find other shoes like this @ cjshoeaffiliate.com) or would you want the page to list off 20 different types for you to choose? Which method would sell more commissions?

Also - if I did the 20 different types, I would just hit the "Get HTML" button on Commission Junction and copy-paste with the pre-written image and description and this would be duplicate content, no? I would get penalized in the SERPs for having these duplicate descriptions that every other site selling the same products is using, right?

Thanks for your help!

Well if your content describing the 1 shoe is so convincing that i want to buy that shoe than i would go with this one.

Let's say your pushing the Michael Jordan Run Fast as Hell Shoe. Tell the people why they need this shoe ( to out run the cops ). Then BAM ! hit them with a call to action.

^Nah that'd be the OJ Simpson Run Fast as Hell Shoe or the OJ Simpson Lead Foot so you can drive away from the cops.

So you guys are suggestion one review.
