As far as overall best quality I would recommend these from Tarot Garden's
Comparison Table.
Green Box 9.5 x 14 cm
Purple Box 7 x 11 cm
Large Swiss Blue Box B (later edition) 9.5 x 14 cm
Pocket Swiss Blue Box 6.7 x 9 cm
There's also a 7 x 11 cm Blue Box that's not on the table.
These are the best available right now in my opinion, and most widely available. They're all printed by the same printer, only the boxes are different for marketing purposes. The instruction booklet in the Green and Purple Boxes is by James Wasserman & Stuart Kaplan. The booklet in the Blue Boxes is by someone else though I can't recall his name, maybe someone else knows.
