Fair price for used Garmin collars???

[BOSS HOGG]

Thinking of upgrading my system so my question is does $100 per working DC-30 collar and 50 per non working collar sound fair? I have no clue what these thing sale for used so was just trying to get a idea of what I'd actually be spending out of pocket on a new setup. Also any feedback on the alpha system pros and cons are welcome thanks.

Thats a fair price. I sold my 220 and 4 dc 30 collars for $500. The down side to getting rid of something that already works is, u hav to start over. The 320 combo i bought was $500 with 1 collar and ea additional collar is $200, bout the same with the alpha collars but the alpha only works with alpha collars as where the 320 works with the 30s, 40s and 50s.
