Mike, welcome to the madness. You have entered the market at a great time. There are some great kits around from the various manufacturers each with their own level of "completeness from a kit perspective" depending on what you want to experience from your build.
There is a neat thread about all the kit manufacturers here:

I'd highly recommend sitting in a few if you can and do a close inspection, cause they are all a little different in their own special way. Then maybe pick your top 2 or 3 and go visit their workshops, well worth the exercise.
This forum is an encyclopaedia (or "google") of information. :-)
Building with an interstate supplier is ok as long as they give good service and answer phone etc.
Have fun choosing.
cheers
Gregg
