Well, there is of course the obvious Thoth, which is a lot more faithful to the original Liber Theta descriptions than the RWS, although perhaps different in spirit.
Possibly the most accurate GD deck available is Robert Wang's deck, with the highly imaginative name of Golden Dawn Tarot. However, the artwork is not to everyone's taste (it certainly isn't to mine) but I'll get it for study purposes someday.
There is a new deck, published by Lo Scarabeo, the Initiatory Tarot of the Golden Dawn. Its drawings are cartoony and scenic, but what is interesting about it is that it is not based on Waite, the artist having no knowledge of previous GD interpretations.
The Hermetic is also interesting, and my deck of choice for comparing the Thoth to pure GD symbolism. A very strange deck, black and white, strange artwork and all in all a somewhat perverse feel to it, it is nevertheless magnificent.
