The used-market median is US$140, with the middle half running from US$115 to US$164, so US$150 is a fair asking price rather than a bargain. It sits comfortably inside the normal range; the unknown condition is the main reason not to call it an outright steal.
The DX3 Pro remains a very capable compact DAC/headphone amp, offering clean conversion, USB/optical/coaxial inputs, Bluetooth with aptX HD, and useful RCA line output. Its headphone stage has enough power for many demanding headphones, while the small footprint makes it an easy desktop or second-system component. Confirm that the remote, power supply, and Bluetooth function are included, and check the display and volume control; with those present and everything working properly, US$150 is a sensible buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
