I found a site that lists expired domain names from 300 servers for free
If the domain name is expired I assume that is the one no one is interested anymore. I do not think that is good idea at all to invest in such domain names. Can anyone please update?
Those expired domains should remain expired 
those at dd.matterr.com are expired on the particular date
Namepros and domainnews forums do have good lists of expired domain names there as well.
very nice site
I suggest this one too [B][COLOR=“DarkGreen”]dotexpireddomain.com[/COLOR][/B] for expiring soon & expired domains
