I want to buy a pmp/pma (personal mesia player/assitant). 
For me, Down the line, there are three model to choose from:
Archos pma 430 - 30GB
Creative Zen Vision - 30 GB 
cowon A2 (iaudio A2) - 20 GB
which one has got the best overall reviews?

hi Uribi...

They are all great PMPs.  But the fact that most of today's video
files are encoded in either Divx or Xvid, will make me go for the
Creative Zen...  Creative is the most recognized brand of them all.

I own an Archos 400 myself, but the software included that you need to
recode divx and/or xvid videos is not very friendly.  I would have
bought the Zen back then if it wasn't for the fact that then the Zen
would only play wmv (Windows Media Videos)...  I have seen the video
quality of my 400 vs 430 in real life and they're about the same.  The
Zen does look a bit better....

The Cowon is the least recognized brand of the three.  That would
worry me some...  I own some other Creative products and they have
great support and warranties.  Archos is based in the U.K., so take
that into consideration....  Creative products are serviced in the
US....

I hope this help you make up your mind...  Best regards,

Carlitos
