Global Surf Industries seem OK and appear to stand up to inspection here in Australia they have a reasonable range from a wide range of shapers so does Surf tech so do some of the other generic board companies .
Surf tech OK too,seems to be entirely in the epoxy range but has shapes from experty type boards to novice basicals as does GSI.
If you are really beginning I think there are two ways to go, good secondhander or a new board from the factory mass producers.
Secondhanders though can have water in them as extra weight and I think will be quicker to reach their use by date.
I'd tend to go finances permitting with a new board
Bear in mind that as you progress you will have ( hopefully) many boards pass through your hands and each will be a statement of your surfing evolution. Some may even be duds but hey you will have progressed enough to tell
IMO when the board is unequal to what you are trying to do, then it's time to change up.
At some stage you will form a relationship with a quality shaper maybe you might have even surfed with them, then the game gets better. Designs begin to be made for your specific needs and maybe even for your specific destinations when you go away.
Now about the good boards bit: think an adequate volume to make paddling easier but not at tanker level, a good glass or epoxy job for durability, a quality adaptable shape to give you an all round go at wide degree of surf conditions.
Specialise more as your skills getup.
Now the Walden Magic Model by its dimensions and and your east coast location could be a nice pairing to begin your journey.
Long answer I know but I get excited about people genuinely starting surfing
