While not as iconic as PSA or BGS slabs, the consensus among the TCG community in general is that ARS has the best-looking slabs out of all of them

Currently the decks are selling for between $60 and $70 on Amazon (check with your local game store, they might have an even better deal) and at this price all of the decks seem like fine buys, assuming you want the new Doctor Who cards
