I found a place that is a Tritronics dealer that is also an authorized repair place for them that sells reconditioned units. I bought the Trashbreaker for my coonhound that has a range of 2miles for half of what they cost new (list at 445. I paid 195.). The company is located in Traverse City Michigan called Collar Clinic and if you go to Tritronics you go to the dealer sites and you will find their site as well as a list of prices of new and reconditioned that they have on hand. The best deal I hear from others is the Tritronics Classic which goes about 299. Mine being older I have to deal with plugs being used which I guess you don' t with the newer ones but I do have the capability of changing my own batteries which you could not do with the older models such as " The Judge" which cost 109 bucks to have " reconditioned" no matter what is wrong with it. I know from experience on this. The bottom line is stay with the better name units like Tritronics.
