No problem!
I think people sometimes don't take into account the different experience levels people have with things like painting.
There are a lot of different paint brands out there, and a lot of different methods of applying them.
For some more inexperienced painters, an airbrush has some kind of stigma attached, like it's something mystical and scary. 
It's true that using an airbrush is a little different than just popping the top off a spray can, but if you mess around with a simple little single action Testors or Badger airbrush (I use a single action Badger, myself) and get some practice, you'll find that it's pretty fun! The one I use was only $20.00 and I've been using it for close to 4 years.
It will certainly give you a lot more color options, instead of searching high and low for certain colors of spray paint.
