I would say TWD pro first choice and Tspp if you can get one in great shape.
TWD pro is fantastic, I don't have much time on TWD premium but you mentioned a budget, that's something to consider because you will want to addd Color DMD which is another $400 for Tspp ($415 for TWD because of the adapter) +$20 shipping.
Tspp (IMO) will never get old and if you are a big fan that's great, TWD is much more brutal and may be more fun if you like a game that fights back and the rules are also great.
I never played GB
