Linux for old PC

Hi,
I have installed Ubuntu on my main PC(high spec). On this PC I have a dual boot with Windows XP Pro.

I have an old PC:
256MB Ram
60GB HDD

I got rid of Windows Home on this PC. I installed Xubuntu. While I am delighted with Ubuntu I am not convinced about Xubuntu. What are your views on the best Linux distro for a my old spec PC? I want to change from Xubuntu to another distro on this old PC. I have heard good things about

Parsix
Pardus
Granular
Blag
wolvix

would any of these be good for my old PC?

Any input appreciated. Thanks.

I see that you subscribe to the same boards that I do...

Try Puppy Linux 3.0.1 it should really run great on your system with no upgrades required.
Click the HARD DRIVE tab for more info.

Take a look at PCLINUXOS 2007. It may be what you're looking for.
