You could try CrunchyRoll. Their website and player are buggy as all f**k, but they simulcast most of the latest shows. Subscription is pretty cheap too.
I would advise not streaming your anime though. At least, if quality is an issue for you, there are much better alternatives. Such as DVDs or BDs, considering you said money isn't a problem, that's probably the best option. You also get a nice physical copy to keep forever and you never have to worry about the stream being taken down if you want to watch it again later.
Though in all honesty, if you're watching anime in 480p, you really aren't getting the full experience. A lot of the latest shows have gorgeous and fluid animation that can only be fully appreciated in delicious 1080p.
