Sites worth buying ??

I have discovered a good way to buy websites before they expire and my intention was to simply sell links on them.

Now I buy these for peanuts, and have access now to quite a few BUT what is the lowest PR website worth buying e.g. PR5 or PR6 or higher ??

Got my eye on a PR5 but they wany $300 dollars for it, it is a 14 year old PR5 site.

Thoughts ??

$300 for a PR 5 site. OMG.. take it quickly.

Your idea is good
Go buy them alot and make your private network .
Add PR2 and PR2+ only to get good response .
