Goober,
Forums are not compulsory and all 300,000,000 US citizens are not obliged to come here daily.
The bulk of the people here come with a problem that gets resolved.
For product reviews it can be a bit patchy because you are relying on some one having first hand experience with the tool you are looking at.
If you need to know if there is a major flaw in anything the best place to look is a product review forum.
Unfortunately nearly all of the reviews will be negative because it is human nature to whinge about what is wrong rather than praise what is good.
So you use the reviews to lean what you should check before you buy a used one.
Good luck with your search for a mower.
