yeah, its overwhelming at first, there's so many out there, but some will appeal to you more than others, so I suggest starting with those, then working your way down to any you may not be so fond of.
Some of the ayupans I really do not like at all are:
#8,
#19,
#22 (mainly because it always falls off my shelf, so I call it my Kamikaze Ayupan),
47 (cos it cost me an arm and a leg and it's not even a real costume from anything!),
#87 (jailbird Ayu?)
