AFAIK 8/26 ep have been released of the second season of gits SAC, 2nd GIG (and as there is still no licence in fr there are available through some fansub team ) Scenario and quality are still vgood.
I have seen only the 1st season of orphen, it is below (not to far but below ) slayers on my fav anime list. Season #1 of slayers look a little oldies nowadays but it is still ok (season#3 rocks !! "Tsu-tsu-tsunami !!")
I have seen only 2 (return & prenium) movies of slayers (called them oav if u want) they rock (quality is better than in tv serie)
