Not Quite An Exact Match Domain-How Much More Difficult?

I found a group of related keywords with a lot of searches and low to decent amounts of competition in exact match. However, the keywords involve a product name, which is of course trademarked so I'm not going to use any of those in a domain name-that would be foolish. There's a lot of keywords that I can use as names for the product review pages though.

The thing I'm thinking about is the fact that I won't be able to use an exact match domain. However, I can use a domain that has most of that keyword, and it would be the generic, non-trademarked name of the general product. I would just need to add a small suffix to the end using one of the Google stop words.

My question is, have any of you ever tried to rank a site where you couldn't get an exact match domain, but the name was fairly close? I could still use the exact keywords for the pages, and there's quite a few products available. I know it's possible to rank, of course, but I'm wondering if anyone has an idea if it might be much more difficult and time consuming to do it. I've never gone after something that wasn't exact match.

Thanks for any suggestions.
