Let me see if I get your point.

Let's say you start a post, saying, while you like Mike 4, you'd rather not spend the money or Runtime real estate on him until you're dazzled, so does anyone know of any other figures, for free or for profit, that are in a similar vein as Mike 4? 

Are you asking if you can link to Mike 4 in your initial post?  I don't see why not.   You're not advertising, you're asking if anyone knows of comparing product. 

However, if you're asking a question about a product, the best place to ask first is the creator of said product, as they'd be able to answer questions better than most forumfolk.  Plus, chances are, only 10 other people have the product, and you're the only one that visits the forums ;)
