[Groop] Groo Collectibles, Memorabilia and info?

[Robert Sawtelle]

Hello,
I'm new to this group and returning to the folds of Groo.  I was a collector 
and fan a very long time ago.  And recently was able to meet Sr. Argonnes 
and have decided to fill in my collection.  I was at the recent Comic Con in 
San Diego as a guest of a friend that's a professional cartoonist.  He's 
also an acquaintance of Sergios.  I've told him many times what a fan I was 
of his work.  But after meeting him and buying one of the darkhorse books, 
'life of Groo'.  I read it on the train home and was suddenly filled with 
the same feelings I had as a 10 year old reading groo for the first time in 
the early 80's.  I decided that I want to read them all.  But I know I'm 
missing quite a few!
I've asked my mom to ship me my boxes of stuff from her place so I'll know 
exactly what I have, but I have no idea what all is out there?
So I thought I'd come here and ask the experts.  I know I have the first 8 
from pc.  And a bunch of the early Marvel/epics.  But how many are there?  
And how many other books and specials have there been?  And lastly, what 
other collectibles or memorabilia is there?
In advance, thank you.
