Was browsing the ebay for some christmas presents to myself, and I noticed this listing for a garmin 500: Garmin Edge 500 Cycling GPS Bike Computer Black Silver 010 00829 06 | eBay . Every other website in the world has them listed for $200.00 . Obviously some will be cheaper than others, but this looks more than 3 std deviations away from the norm. What do ya'll think? Seller has good reviews, over 9k feedback, ect...

Thoughts?

Looks like it might be a refurb. Condition is "new other". Even so, I would buy it. Love mine and its a great price. I'm tempted to buy a second in case something happens to mine

I got one new 6 months ago or so on sale for $150, so $139 isn't that far out of line. The going price has dropped since the intro of the 510 and at the time some stores might have been clearing out excess inventory. If you're hesitant on the eBay deal you might shop around more and wait and see if a sale crops up.

I bought a refurbished one on amazon from a third party vendor recently for $135. Looked brand new, working fine, comes with a one year warranty from Garmin. I feel better knowing Amazon would help with any problems. I paired it with the Garmin magnetless sensors, which I had to pay full price for, very easy to setup.

Make sure it is a U.S. version.
I bought a new Edge 500 on EBAY a few years ago and when it showed up, it was a TWN version. Not a huge deal but some have reported quality issues with those. Mine works great but updating the firmware has been a little tricky.

Amazon had a stupid sale when I got mine....200$ for the bundle, brand new. But that price is worth it assuming it works and is the US version.
