Custom Tooltips/Bubbles in Google Maps V3

I know there's pdMarker(http://www.pixeldevelopment.com/pdmarker.asp) that开发者_运维知识库 works wonderfully with Maps API v2 to produce custom tooltips and bubbles. But how about for V3?

Right now pdmarker works perfectly fine for V3, you just need to use V3 methods when working with map:

google.maps.event.addListener(marker, "mouseover", function (e) {
    ib.open(map, marker);
});
