I have a used DC 30 collar that is selling on Ebay this morning. It is bringing only $63.00 at 7:30 this morning. I listed it as a Used DC 30. Last week I sold an identical DC 30 and it brought $150.00. The only difference is the wording on the listing. Anyone who sells on Ebay needs to use the words Garmin, GPS Coon, Hog, Fox and Coyote hunting to attract potential buyers who are searching for a GPS collar.
I also have a refurbished Alpha and a refurbished Astro 220 that will sell this morning on Ebay. Both look to be going cheap at this time and both work good with a 90 day warranty.
