I do not. In Seattle, there are many good vets, but they tended to be expensive, and one ended up getting bought by a large corporation and started offering pet insurance, which they said would lower one’s total expenses over the lifetime of a pet, but IIRC was for care by their company, so IIRC it also locked you into using them, and it seemed like it would have been good to have purchased when the pet was young (and didn’t likely need much medical expense) but was likely not a so great deal to get late in a pet’s life.
If I had a young pet and was planning to stay in one place with a similar sort of vet that I liked, I’d consider it.
But I have the impression that (like other insurance, and like US health care for humans) it’s the beginning of a path to disastrous exploitation, because for the most part, the insurance industry’s purpose is not to make everything more affordable for everyone else – it’s purpose is to make as large a NET profit as it can for itself and it’s stockholders, and that’s ON TOP OF all the administrative costs of insurance complicating medical billing and requiring office building full of insurance industry staff and medical administrators managing paperwork and accounting and all that added gobbledigook.
Another option is to find a good but much cheaper vet. For example, some rural vets are much cheaper than vets in big expensive cities.
