I see a used one on eBay with the mini collar. Bid on it right now is $400. I saw a used one sell on another site for $550. For $100 I'd buy the new one and have the full warranty. I you are in no hurry watch for rebates on them.
I have the mini collar and you lose very little if anything with the mini versus the standard.
Thanks, I've found a mini locally for $530 I think, lady bought it in a high rise apartment building, found it doesn't work there, not sure why she needs it in such a place. But still debating new vs saving some $. I've heard the longer range and longer battery life are nice features. I hope to never have my griffon that far away, but who knows.
What breed of dog are you going to be using the collar on? Garmin states that the standard collar has a battery life of 24 hours versus 16 hours for the mini. In reality who runs a collar on a dog for that long before charging it so battery life is really a non-issue. Garmin also says the range of the standard collar is 9 miles versus 4 miles for the mini. However, in real life tests that have been conducted the difference in the effective range of the two is minimal. I'm not trying to talk you into a mini, just telling you the facts so you can make an informed decision. If you can buy that local Pro 550 plus mini for $530, and it's like new, I'd be all over it. I don't think you will find a better deal.
