What he means is that it's next to impossible to give that kind of advice (beyond generalities) without some more insight into the product/site itself. Because it is all relative.

I would focus on affiliate sales through the site; it makes more sense.

Also: expand the network into other cases like you said in the other thread. That way you should be able to build up a big base of traffic across the niche.

Then you'll probably have more success selling targeted advertising space (i.e. case manufacturers who cover the whole niche)
