Anyone have experience with air pumps listed on eBay and Amazon. Some are as low as $150.00 and go to 4500 psi?

If you are speaking of the Yong Heng compressors, they are common among the members here. Be careful of the knock offs. Some can be not so good. But I'm sure you will hear a typical reply..... "You get what you pay for".
A clue of a true Yong Heng would be a spec plate bearing the Model number QB-01.
