Frozen Terror Nocturne is by far my favorite. The in game look of it is gorgeous. Runner ups: Winged Hussar xin xhao Loch Ness Cho'Gath Debonair Jayce - too bad he sucks atm and I can't find the motivation to play him

tear into muramana > then either maw of malmortious(sp?) or essence reaver depending on the match, cdr boots and lord dominkes maybe steraks if i feel i need a little beefyness
51 skins on 49 champions.
Favorites are Woad Scout Quinn, Snowday Syndra, Abyssal Nautilus, and all of Katarina's

Can't remember how many I have (~20), but my favorites are:

(old and new)
Road Warrior
Astronaut

Admittedly, I often purchase skins simply because I like them even if I rarely play the champion (especially if the skin is on sale). Even if I don't frequently play them, I prefer to have my favourite skin available for them when I do and money isn't really an issue.
Then again, there are a few champions whose default skin is (in my opinion) better than their alternative skins. For example:
