Another bit of advice, take everything you read on this site with a huge pinch of salt. I would say the grumblers out number the happy chappies by quite a ratio. Most grumblers seem to hang around in this forum. Read all the information listed by old scroggsy as this will tell you what you are getting yourself into. Keep your eyes open and for gawds sake don't pay for any course up front, however attractive it looks on paper.
Good luck
