Not sure what the etiquette for this forum is, but Thanks for your ringing endorsement.
I also quite like the Abridging of Haruhi Suzumiya, and I agree with you that nothing else could really have worked for Haruhi.
I haven't seen Wedding Peach Abridged, but from your description, I think I'll check it out. (I quite liked Sailor Moon Abridged.)
I would do my own list, but I have to figure out which ones of my favorites are still on You tube. (Alas! I will not stop grieving over the loss of Prodigs FMA Abridged.)
