If you only need the buying answer, rental is still the lowest upfront route. The paperback remains a strong ownership choice because it is only modestly above rental while sitting far below the broader sampled new-print market, which is exactly the kind of spread that makes a keepable engineering copy worth considering.

The key comparison here is not just print versus rental. It is current print versus the wider new-book market. When a new copy lands only a little above rental but vastly below the other new-print references, ownership becomes much easier to justify for a subject that tends to return in later engineering work.
What this book actually teaches
Control Systems Engineering is a core engineering text built around feedback, block-diagram reasoning, time-domain and frequency-domain interpretation, stability, design procedures, and worked system examples. This is one of those books that often becomes more valuable after the class starts to get difficult, because students need to revisit example logic, diagrams, and problem-solving structure repeatedly rather than just read linearly.
That repeat-use pattern is why ownership matters here. Control systems tends not to disappear after one exam. It often reappears in later design courses and in practical engineering reasoning across electrical, mechanical, aerospace, biomedical, and related fields. If you are certain you only need short access, rent it. If not, the current paperback is one of the better engineering ownership prices in the current market.
Who should buy print and who should not
Rent if your only priority is minimizing one-semester cost. Buy print if you expect control systems to return in later coursework or design work, or if you know you learn best by keeping a heavily worked engineering text. The current paperback price is strong enough to make ownership the better long-term decision for many engineering students.
