Interesting discussion. To me, Ken, it depends on what you’re good at.
For instance the pure mini site model requires you know how to drive traffic to your mini site - affordably. Probably using PPCs, ezine ads, article marketing and the like.
While marketing using a web site theme requires search engine optimization skills so you can land top search engine ranking. Which in turn drives traffic to top ranked content pages with in-text links to your sales letter.
And you don’t need 50-200 pages either. Depending on how competitive the market is, sometimes as few as 10 high demand/low competition pages will suffice. Each reinforcing a popular but harder to rank in focus keyword. Pushing it to it to a top 10 search engine ranking. BTW, to find out how competitive keyword phrases are, you can use the FREE Keyword Competition Wizard, http://www.aboriginemundi.com/kcw/. This tool will tell you how stiff the competition is and how likely you are to attain top search engine ranking. Try it. You may like it.
Anyway I tend to go with what I call "Robust" Mini Sites. That is 15-20 pages of content focused on a web site theme with each content page designed to both rank high and drive traffic to a sales page. Which I also market using ezine solo ads and article marketing.
Hope this helps.
