Registering Expired Domains and what to pick

[rambo3]

i have registered my own domain names but now want to try registgering expired names in the hope of aquiring domains that will earn more money than new domains when parked.

What are the most important things i should look for in a good expired domain.

Established links? what is the minimum you should consider. E.G is less than 100 worthless?
google page rank? is it important for parking?

Any help is useful.

Thanks.

Google PR is definitely an important thing to look for.Linkpopularity is important too. If it is listed in Yahoo Directory or DMOZ then its a big plus. Look for Alexa rank too
