They are still cheap… but it’s because they use single stage for all the gangsta jobs. You can pay (a lot) more and have base/clear done @ Maaco, but it’s up with a normal body shop’s price.
As far as good cheap paint goes, Trinity 1942 brand sprays nice and looks amazing for the money @ paintforcars.com, also Summit Racing sells their line of paint that is rebadged Kirker and that is decent too. The only problem with either is you will be limited in color choices.
My cousin can paint if you are looking for a cheap job. He is probably not as thorough as Mike, but he can lay metallics just fine. He paints professionally at a shady car dealership (LOL).
