I've got a soft spot for OXO products and was about to buy the "OXO Good Grips Pro Swivel Peeler" but then thought I'd check here to see what others recommend for peeling lemons to use as a twist for cocktails.... I've been using a Y-peeler and it's not ideal. When I use a paring knife, I inevitably get too much pith on the peel. Derek Brown uses a swivel peeler and I can't for the life of me remember which brand he recommended.
Incidentally, the lemon twists are for my new favorite cocktail that I've been drinking nonstop for about a month -- the Vieux Carre Cocktail (recipe courtesy of a seminar I took from the Museum of the American Cocktail):
3/4 oz rye whiskey
3/4 oz cognac
3/4 oz sweet vermouth (Martini Rosso)
1/8 oz Benedictine (I use more - yum!)
2 dashes each of Angostura and Peychaud's bitters
Build drink in rocks glass with ice, stir until chilled and garnish with lemon peel.
