Yugster offers the refurbished Cobra SPX955 Radar/Laser Detector with POP Mode Detection for $29.97 with free shipping. That's the lowest price we could find for a refurb by $5, and $70 less than the best deal for a new unit. It features tone alerts, a signal strength meter, city/highway filtering modes, Ku-band detection, and a POP mode (super-fast) for instant-on radar guns.

Note: A 30-day Yugster warranty is provided.
