I definitely would not start out at $150 worth of paint.

Get a starting selection of base colors like this one from vallejo or this one from Citadel/Games Workshop.

This is a decent set of washes from Vallejo to buy in addition to another set. The gray is nice for stormtroopers/clones.

Then buy paints as you need them. This will save you from buying a massive set where you won't use half the paints.
