Here are few I really want to get:
La Cordo D'oro Primo Passo
Story of Saiunkoku
He is my Master
Star Ocean EX
You're under arrest 2nd & 3rd seasons
Irrisponsible Captain Tylor
I actually have a hand-written list of anime I want to buy, this is just from my A-list, I've got a D-list as well.(Scary I know.)
But all the titles on your list seem fine to me. To me "suckage" is very subjective: I've seen quite a bit of anime and very rarely have I gone: "That just sucked; I want meh money back!".
Most of the time when I get dissapionted with an anime it was because of one of two things: I either fell for a series hype, or the much dreaded and oft loathed "non-ending" reared it's ugly head. Many many an awesome series have sucumbed to that evil beast.
epp...Sorry for the rant.
