I second Nektu on this one, GBB isn't something that's usually very chilled out and are pretty quick to shoot hairs. I LOVE LOVE LOVE Chaco Golden Knees (Grammostola Pulchripes) but they, like almost all Grammostola, tend to get some pretty severe mood swings from time to time. Another group you could look at are the Brachypelma. They've got some pretty stunning lookers, and they tend to be pretty docile as well (though of course there are always exceptions) and aren't hard to find.
