Hello, I am also from MA and have heard of Clover Hill (not sure how they are) and I know Shenanigans is a very reputable breeder. When we were looking for a Yorkie, we went with a CT breeder who had a pup available when we were ready. I can give you her name if you are interested. I know our breeder just had two recent litters so there could be something available soon.
Good luck in your search.
