Тhe http://tool.domains startup has the goal of monitoring every domain name in the world in order to find (among other things) all good expired domains with natural backlinks among all TLDs. We currently have lists of over 50 000 free domains with Majestic Trust Flow 10+
We can find you thousands of dropped old domain names with good authority (I suggest Trust Flow 15+, Referring domains 10+), that are currently free. This is a very cheap service, costs only $10 per each domain you actually like enough to buy - you buy the domain yourself and pay us $10 (bulk discounts are possible for over 100 domains). This is very good if you need a lot of good old domain names eg. for a blog network or supporting websites. You also take zero risk, because there is no upfront cost and you only pay for domains you like.
Here is how it works step by step:
1) You tell us the metrics the domains should have. Usually they have no Pagerank, but some do. In my opinion the best filtering is Majestic Trust Flow 15+ and Referring domains 10+.
2) We give you some (say 50) free domain names, that fit the criteria. The process is automatic, so not all domains will be that good - a small part will have low quality spam links, etc. But the average quality is quite good - way better than all free or paid-subscription websites for expired domains.
3) You look through the list and decide how many domains you want to buy (say you like 16 out of 50). You buy the domains from your chosen registrar and pay us $10 for each domain name you liked ($160 in total) for the information we gave you.
This way you don't risk anything, you only pay for what you truly like.
