I've done this before, but here goes....... :)

1) How long have you been collecting cels?

Three years.....wow.....has it really been that long??? O_o

2) How much do you spend on cels per month? (Average)

*TOO* much! Maybe $300 the way I've been buying!

3) What is your favorite cel? (Post pic)

Who else? Kaori! See below!

4) Assuming you buy cels off the internet - what is your
   favorite site to buy them from (not necessarily where
   you buy cels most regularly)?

I buy from so many different places.....I can't decide. ^_^

5a) Do you concentrate on specific characters or series or
    both?

Both! Sailor Moon and Card Captor Sakura! Kaori! Kaho!
Sakura! Nakuru!

 b) If you collect for a series, do you go through the
    trouble of finding at least one cel per character?

Yup, I'm working on it! Something tells me I'm never going
to get a Yue or Nadeshiko or Ruby Moon cel, though.

6) Have you ever purchased a cel from EBay or Yahoo or some
   other auction site?

Yes, with mostly good results. :)

7) Do you have family members who also appreciate cels?

I have a couple of cousins who think it's cool...the rest
just think I'm loony.

8) Do you have friends who appreciate cels?

Only internet friends. :>

9) In the space of this form box (i.e. the entire message
   cannot force scrolling either vertically or horizontally
   in the reply text box), please explain WHY you think
   cels are so addicting - imagine you're trying to explain
   to someone why they're so great. 

It's like owning the character! ^_~ Or owning a little piece
of the anime you're collecting from. There are so many
different characters and poses and scenes to hunt down and
buy! Or maybe it's paint fumes. ^_^
