I always go on these:
link (this site's great for speedy updates, but it's been known to lag and have formatting issues; however, it's also great for finding new Аниме to watch -- my first choice for finding new series)
link (I Любовь this site because, it doesn't have just episodes for streaming, but downloading too. An AMV maker's absolute best friend! Also, this site's not too bad on speedy Обновления too)
link (this is the site Ты go to when Ты JUST CAN'T find the series online. The selection of series on this site is so amazing! Problem is the pop-ups and ads, but if Ты get passed it, Ты have a perfect Источник of online anime)
To a lesser extent, there is also:

^_^ I hope that helped~!
