The Maiden marked decks, as produced by Rick Lax, have larger markings on Bicycle Maiden backed cards. They are marked in 6 places and depending on the version you get are available with various Mnemonica stack cribs hidden on the back of the cards, extra gaffes, or even tappered decks. All of these for about $10 for a single deck and $5 if you purchase the decks in bulk.
The Ultimate Marked Deck is a bit more expensive, but it uses a Bicycle rider backed deck. The markings are a bit smaller and there are only 2 per card.
