Darky...don't be put off by the RAA bashers.
Instructing is a great thing to do (for some) provided you have a passion for it. GA (for instance) is riddled with CPL's with IR's ....only trying to build hours and then move on. They really dont care about the student or their progress.
Once you have your rating you will be closely monitored by a CFI to ensure that you are maintaining a good standard and developing your personal instructional skills.
Weekend instructing is fun. It is a break away from the Monday-to-Fridayitis and keeps your flying and people skills well honed. (you may even be able to pay for the fuel you use to drive to the airfield!!)
The majority of RAA students are doing 'it' because they have always wanted to but found GA (costs and regulation) was too hard.
Learning to become an Instructor will teach you a lot about yourself....take the challenge.
