Accessible install of Sid or Dapper?

[Ricky Enger]

Hi all,
I'm interested in checking out Debian unstable or Ubuntu Dapper 
Drake, and was just curious about the cleanest and most accessible 
way to install these distros.  I know about Brltty, but since  I 
don't have a Braille display, this solution won't work for me.  I 
know there's a Speakup-modified Sarge and one can upgrade to Sid from 
that, but are there any caveats I should be aware of with that process?

Since I know that there are several on the list using Debian 
unstable, I figured this was the logical place to ask, but if there's 
a more appropriate place to post the question I'll be happy to do 
so.  Thanks for any suggestions or ideas.
