For romantic readings, I very highly recommend the Lover's Path Tarot by Kris Waldherr. Painted using rich oils on watercolor, they bask in a warm, magnetic glow that more than amply evokes the strength and ferocity of the universal sentiment that this deck seeks to celebrate: Love. Passionate, sensuous, and utterly compelling, it is perfect for love and even general relationship readings. I find it very much readable, and even if I'm more of a left-brain person, the Lover's Path is very effective in stimulating my intuitive faculties. This is definitely one of the most sublime and glorious decks I've ever laid eyes upon.
A few of the cards are shown here, and yes they are as rich, lush, and vivid as they look:

The next link shows my favorite card of the deck, from the atu of the Chariot, which in the Lover's Path celebrates the romance of Tristan and Isolde. This is the Card of Desire:

In the Tarot.Com site above, if you click on the left or right cards beside the central image you may be able to traverse the whole deck and see all the cards for yourself. Of course, since these images have a low resolution, they cannot do justice to the actual cards.
