As a reader discovered, AltaTac via Rakuten Shopping offers the refurbished Magellan RoadMate 2230T-LM 4.3" Portable GPS Navigation System, model no. RM2230SGLUC, for $44.99 with free shipping. That's tied with our August mention (which included lifetime map updates) as the lowest total price we've seen for this GPS. (It's also the lowest total price we could find for a new unit by $67.) Features include a 4.3" touchscreen LCD, text-to-speech, voice prompts, and parking function.

Of note, no warranty information is provided.

Update: The price has now dropped to $39.99, making it the best price we've seen for this model.
