Word of warning, titles can be duplicate too. If there are already 500 pages on Google with the exact same title, by people looking to score for a particular keyword, you'll only return a couple at most in the top 10 before Google wants to mix up the titles. A page full of the same titles would tell searchers very little.
So, mix it up yourself. Have a page with an exact match for a keyword? good, now go write a few about smaller aspects of that keyword and make sure it's an interesting read. Nobody wants to read something that starts with... "KEYWORD are sometimes sold online, especially in KEYWORD stores and are bought by KEYWORD collectors for their KEYWORD collections". Bleh!
