Macross Plus is another really good one, it's split across two DVD's but they're more than worth watching. I still don't own them, but I do plan to pick them up someday.
Ooh, forgot about that one. Macross Plus is awesome with one of the most amazing soundtracks I've ever heard.
I also second warning's recommendation of Macross Zero- hopefully it gets licensed here but, if not, its well worth the minimal effort to track it down fan-subbed.
I own Bloodlust and while its beautiful visually I have a hard time staying away from it.
For pure visual porn (not *that* kind of porn) it doesn't get much better than Blood: The Last Vampire. Not worth a purchase for most (its only 40 minutes long and not exactly deep) but I think its pretty damn cool and I'm dying for a sequel.
