Yes I think far and away most schools employ fundamentally honest people. Without doubt and like many busineses, there are the good the bad and the ugly. Usually it doesn't take a great deal of research to find out those that stand out in any of these categories.
One of the problems with this particular industry, is that some customers have wholly unrealistic expectations of just what it is they are buying. Despite plenty of advice and warnings, it is an industry that seems to attract a very large contingent of woefully naive and hopelessly under researched individuals. Clearly this provides rich pickings for the unscrupulous service providers that do exist. However it also results in some schools being wrongly labelled by individuals who simply picked the attractive bits of the "label on the tin" in an attempt to satisfy their own expections.
I'm looking for "Ab-initio, Zero to CPL/CFI JAA & FAA"
There are plenty that satisfy that requirement. The reality is though, that people gloss over little words like "from" and only focus on the headline price. Likewise they fail to pay much attention to the exchange rate illustrated when foreign currencies are involved. Similarly they fail to allow for the fact that time and cost requirements vary from person to person due to a host of variables. Then they assume that "Ab-initio, Zero to CPL/CFI" are somehow two ends of a magic yellow brick road, with rewards waiting at the end of the journey. Usually that is far from the reality and often the point that reality actually begins to bite. Often the anger that comes with that reality starts to be directed at those who were only to happy to accept the business.
Do your research carefully, and decide what is right for you.
