Сейчас использую blueprintcss, reset примерно такой (очень похож на каноничный http://meyerweb.com/eric/tools/css/reset/):

html {margin:0;padding:0;border:0;}
body, div, span, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, code, del, dfn, em, img, q, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, dialog, figure, footer, header, hgroup, nav, section {margin:0;padding:0;border:0;font-weight:inherit;font-style:inherit;font-size:100%;font-family:inherit;vertical-align:baseline;}
article, aside, dialog, figure, footer, header, hgroup, nav, section {display:block;}
body {line-height:1.5;background:white;}
table {border-collapse:separate;border-spacing:0;}
caption, th, td {text-align:left;font-weight:normal;float:none !important;}
table, th, td {vertical-align:middle;}
blockquote:before, blockquote:after, q:before, q:after {content:'';}
blockquote, q {quotes:"" "";}
a img {border:none;}
:focus {outline:0;}

С YUI как-то было дело, но там многое раздражает (li list-style:none убивает) и многого не хватает (того же a img, :focus, blockquote, HTML5).
