I'm an avid researcher before I buy, and I agree with Phyl. Most important, though, as with any type of research, is to read and compare multiple sources to look for agreement and disagreement. Just think, for instance, of how people at this forum regularly disagree on nearly every issue raised. Pro reviewers, regardless of their level of bias, do the same.
When you find general agreement across sources (e.g., about the bang-for-buck of Studio Projects budget mics), then you have something meaningful although even then, in the end, your own personal review may differ because of your specific tastes. But it's a fun and rewarding search, nonetheless.
Best of luck,
J.
