Thanks to those who posted a reply or PM'd me some info. I thought I'd post an update here, so that if anyone else has the same dilemma, then this could perhaps be of use :) Ok, so here is what I have learned...
I have now pulled the trigger on lessons and am so far 2 hours into it :) Great fun.
I was recommended Christian (kitebud.com) by a few people, and it seems that he is the overwhelming crowd favorite. The
only reason I didn't go with him was that a mate of mine and I decided to have a crack at this together and we went with a school that could give us 2 instructors at the same time (not being instructed together, just the same time on the same beach). I was also unable to do much research on lessons through Christian's website (kitebud) with no info on price per hour etc.. Not a big deal, but I did do a fair bit of research online before I started calling around.
Other than Christian, the schools that I received positive feedback from were; WestOz, WA Surf and Action Sports (North of the River). I'm sure there are plenty of other good experiences out there, so consider these guys a part of a bigger list
I live north of the river, so Rockingham isn't the most convenient, but I did eventually decide to make the longer trip down there, as everyone I have spoken to has said it is pretty much the best place to learn. I won't say who I went with, as I'm only 1x2 hour lesson into it and I have no reason to think that these guys are any better or worse than the other school down here. I am however, very happy with my choice so far.
I was attracted by the offers that many schools are making, of "get the value of your lessons off the cost of equipment" or "special price for our students", but I wouldn't recommend to anyone that this be a part of their decision process, as it is pretty much a scam, or to be more fair (that was way harsh) - doesn't really work the way you would initially (naively) want it to. All the stores will generally sell you a package at the best price they can and the special deal is only off full RRP, with their existing packages that is offered to everyone being a better deal already.
Cheers
