Hey,
You can try the wonderful SLAX which is also a
livecd that I use for all of my rescue work!
www.slax.org/
If you want a live cd that is slackware based
go for SLAX, but you can't install it to hard
drive!
But if you want something that you can install to
hard drive then go with vector linux. They have
a live cd which you can try out and if you like
it then download their install cd and install!
It is slackware based so that means it's still
slackware,they just added stuff to it so it's easier
to install and operate.It also has a package
manager.I've used it before I started using pure
slackware and it gave me a good start in linux.

and they have their own forums too.
But if you still want something else then
google "slackware based live cds"
or "slackware based distros"
Good luck
