"I found the installation of Replicant on a Samsung Galaxy S2 to be nearly
trivial. Unless it is harder to install Replicant on a tablet for some
reason, the OP should be fine buying a Galaxy Tab running Android and
installing Replicant themselves."
If that's the case, then here's the page with installation information:

I see from it that there's another supported tablet, the Samsung Galaxy Note
8.0. I'm not sure why that tablet is not on the list of supported devices in
the first link of my previous post.
