I ran Parsix sometime ago, and really liked it. With my little dialup, can't do any downloading,...so have to wait until the CD comes out. It's a high-quality Debian-Testing-Based distro all right. The only problem that I have with it,..is the forum. The devs are extremely helpful and friendly,....but there is almost NO other activity going on there (you can almost hear the crickets, and watch the tumbleweeds blowing by).
EDIT: I just re-installed Dreamlinux 3.5 on another P3,...I find I actually like it quite well. Must be that good ol' "Debian-touch". It goes very well on that old computer,...think I'll leave it there. (It's not bad at all).
