Is a parts unit worth buying?
The $399.99 parts price is $150.01 less than the $550 working asking price — a 27% gap. Whether that gap covers the cost of repair depends on what's wrong.
What "for parts" usually means for a cassette deck: Cassette decks for parts usually need belts and pinch rollers (routine), or have worn heads, sticky mechanisms, or failed motor circuits (more serious). Head condition is the critical variable.
When it pencils out: Belt and pinch roller replacement costs $20–60 in parts and a few hours of work — completely worthwhile if that's all that's wrong. Head wear, however, is not repairable. The $150.01 gap makes sense to pursue if the heads are confirmed in good condition.
When to walk away: A deck with worn recording/playback heads is the core parts-deck trap. Head condition isn't visible in listing photos. Ask the seller to describe the record/playback quality, or inspect in person. Replacement heads for most models are unavailable or prohibitively expensive.
DIY vs shop: Belt replacement is a moderate DIY task requiring patience and the right tools. Head alignment requires a test tape and an oscilloscope — not a beginner job. Full repair cost context: what vintage stereo repair actually costs.
