Ditto--no wrong decision if you decide to go with either a breeder or if you contact your local golden rescue or animal shelter. You're up in NJ and there should be several reputable breeders in a three, four mile radius of where you are, I would guess.
If your mind is made up on a puppy, and if NJ is anything like South Florida, where I'm sitting, it will be quite some time before you'd have any pups to choose from in rescue--older goldens, like 2 or 3 years old--definitely, but puppies are very rare. So I believe your husband is correct--if you decide to go through rescue or a shelter, it could be a long wait.
However, if NJ is like Florida, be prepared to whip out a stack of Benjamins if you decide to go through a hobby breeder. A pup whose sire and dam have all the recommended clearances does not come cheap--at least not here in S.FLA and I would think NJ would be no different. Expect to pay anywhere between $1500 and $2000. If $$$$ is a strong consideration, then the wait for a pup or even a younger dog from rescue doesn't seem so long.
Either way you go, you're choosing a great breed. The first golden my husband and I lost, we also lost rather suddenly like your family, and it was around 2 or so years ago. My Alli's ashes were maybe in the house for only a couple of days when I learned through a friend that Alli's breeder was breeding one of Alli's half-sisters. Although we were still grieving, it was almost as if it was meant to be, and we are so happy with the joy that our young golden Mac brings us every day. Although she's not all that much like Alli, she's got some of her traits, and it's like, in some ways, she's still here with us. Good luck to you and your family.
