I have been a ground walking creature for too long now and would love to take to the skies!

I am seriously considering buying a microlight and learning to fly it.
However I just need some advice from the old hands in microlights.
Firstly, what is the best? should I buy a microlight first and then get my licence flying it, or should I first enrol for licence training and then buy a microlight? I would love to hear your thoughts on this.
I would also like to know which microlight you would advise on purchasing, I think this almost like motorbikes, buy the right size and type to start with? which ones are popular and good?
I stay in Newcastle and I am planning to enrol at ladysmith KZN flight school for my licence. Found their web page.
Unfortunately Newcastle does not have many microlights and I am struggling to get guys to take me out for a couple of flips. either the weather or time is never right. any volunteers? I will help with the petrol. I am 54, but if anyone calls me Oom, then I will fly back on my own.
Cheers
Trevor
