I agree with Swanny, that Testors airbrush is just an Aztec with a different name on it. I would go with a Badger but I would buy it elsewhere as Tower Hobbies is more expensive than somewhere like Coast Airbrush, Dixie Art, or Bear Air.
By the way, that Badger Crescendo is only $69 with free shipping from Dixie Art.
Do you want a gravity feed or something that does both like the Badger 360 and Omni Matrix? What kind and size of models are you going to paint?
If you are going to be painting big models like 1/32 scale aircraft or the 1/48 scale C-130, etc you will need a siphon feed so that you will have enough paint on hand.
These factors will help in deciding what you might need.

“Wisdom is the right use of knowledge. To know is not
to be wise. Many men know a great deal, and are all the greater fools
for it. There is no fool so great a fool as a knowing fool. But to know
how to use knowledge is to have wisdom. " Charles Spurgeon
