Expiring domains with PR, what's the snaping point?

[dpk87]

Say you find a domain that has PR and is expiring, at want point is it pretty much gauranteed that somone, somewhere has snapped it?

PR 3? 4?

I got two PR7 domains a day after they were deleted, but the PR does not stay... at least for the 2 PR7's I reged.

If you get a domain with pre-existing links that should help your PR in the future, but I don't think you will get instant PR. If anyone has more info on this I would like to hear how PR works with expired domains.
