The best thing to do my friend is have a good look around through search engines, go to the flyer exhibitions or similar and have a good read on here. Picking a school is down to personal preference in the end really, like choosing a phone or a car! There's many and you'll hear good and bad things, like everything in life. As long as there's not too many bad experiences you have many schools to choose from. When you have narrowed down the schools you like the feel of, then you can read/ask on here to see what other people have experienced. Going for a visit is good if you have the time/money.
Start your research and ask questions along the way. If you use the search facility you'll probably find that most of the questions you will have have been asked before. Other people will only be able to give you thoughts based on their beliefs and experiences which may not match what you experience but getting as much information as you can will allow you to make a decision that is right for you.
Good luck
