Forums, they're addictive but informative.
If you're looking to buy a new piece of equipment, unless you have no idea what to look for, posting on forums is very helpfull, but if you already know what to look for, posting for help will confuse you to the point you have to forget about it for a while, take a break and then start over again with your search and decision making, that's the way it works with me, I don't know about others.
