BestFares? Yep, use it all the time. It rocks. And yes, it is worth the fee. Hell, join for a year and make one trip and you've more than likely paid for the fee. Also, I edited your post to fix your typo (changed BestFaes to BestFares)
Yep. It's not like PriceLine. You might have to be a little flexible in your plans to get the absolute lowest prices, but BestFares rocks.
I'm seriously considering using these guys. you aren't flying crap airlines are you? I don't want to plunk down $60 to join if I'm going to have to take a plane with a duct-taped wing!
In some parts of the world you'd have a hard time finding an outlet to plug your glue gun into. It was a valid question.
