We’re glad to see you here! Another thing that occurred to me is to shop around and get a lay of the land before you buy. See what vendors tend to carry what you’re looking for and what the price points are. Take a look at the Nurseries List in the Reference section, most of which are at least pretty good. Some of them are members on this forum. Also look for Garden Watchdog reviews of nurseries. And stay away from TyTy!
Whenever you do buy trees, if you get already grafted, a small bare root or potted tree will establish better and be healthier than an extra jumbo super size, on average. The small trees will often quickly catch up with their bigger, pricier kin.
