What course is right for me?

Hi everyone, looking for a bit of help, I live n the UK in Berkshire, I have just been accepted on my college course to do NVQ level 2 hairdressing and am currently working as a junior stylist in a salon, I am looking to  take a hair extension course but am worried I am going to get ripped of, does anyone know of any good training out there being offered, I am looking to keep the price below £450 if possible, I was thinking of Balmain which is £275.00 or Hairaisers at £395.00 but am a bit scared of travelling into London, any others???? If you know of any that train in your own salon too and give cheaper rates to colleges that would be helpful too, thanks guys, look forward to hearing from you. :)
