Mike,
The Paasche Model VL Double Action is all you'll ever need.
I would first shop on Craig's List.
The jam gun from Harbor Freight but don't buy a HVLP.
Compressor? The bigger the better.

In all honesty you really don't need any of that stuff to produce a great finish on your models.
All I use is aerosol cans. I've put up enough photos so you must know of the quality in results I get.
I suggest you first try a good aerosol can finish before you invest in spray equipment.
Keep in mind, I have a life long relationship with professional spray equipment including the airbrush, yet I elect to use aerosol cans. And I still have equipment.
Nothing to open and mix and no cleaning. Definitely a money saver., a big money saver! Save a bunch of time also.
I have info on Krylon brand over at CFC Graphics vendor's corner with photos.
