I recently rented Tatsunoko VS Capcom from Gamefly, and it ignited my interest in this Anime production company. I’ve since rented both Karas movies from Netflix, and loved them, and I currently have some of Tekkaman Blade from Netflix, which is interesting so far.
I’d like to know what else from Tatsunoko I should search for. Can anyone recommend anything? 
According to Anime News Network:

K?ch? Buranko (TV)
But, I haven’t seen it.
