Here is another methods:
I look at
who is writing about the product.
After reading many posts, I've learned who can really be relied upon.
For example (and this does not include everybody) I know that any recommendation from the following guys is golden:
Bryan OHaleck, Ken Snow, Jim Martin, Larry Capitoni- These guys will tell it as it is.
And on the suppliers side: Scott Warrington, Larry Cobb,
John Olson
Also, Jeff and Les tend to engage more in promoting their products, however they will always help out and give honest and great advise, whenever you need it.
These are just a few that gained my trust.
Yes, lots of self promotion, lots of good advise.
Develop your "trust" list.
