Ryanair has taken the low-price aspect to an extreme too. For the flights I care about, it's generally something like £5, but once in a while it's literally £0 plus airport fees. I have never been treated particularly badly by them. You don't get anything that might be included in a more expensive flight such as checked bags, a meal, assigned seating, etc., but I don't really care about those things anyway, certainly not for 1-3 hour flights within Europe.
