Internet cash advance?

This question is for a friend, because I have heard of people getting burned, is there an internet cash advance place that actually charges a DECENT rate and doesn't rip you off too bad. He is needing some extra cash and has showed me a couple that he checked into, but my gosh they are going to charge him $90 to borrow $300, and then charge a $50 fee when the check comes due in 2 weeks. Are they all like this? Thanks and please list a source if you can.
