I have seen first hand where a company has hundreds of complaints and is pressured by the BBB. The company becomes a member, buys the local BBB office new computers, and voila! The company couldn't have a better reputation.

The BBB is an absolute scam!

Word of mouth is probably a better guide. There are a lot of folks that have done business with Ammoman, including me. You can often find what he has for cheaper, but sometimes he has stuff you can't find from others.
