The only problem I've known with the Brachys that they grow slow,and I know the same with the pulchra.But hey,I started with a L.parahybana(Right now about 2 inches in legspan,known to get to 10"-Crazy one of the bunch),A.geniculata(Same size as other,but only grows to around 8?".), and G.aureostriata(mellow,pretty small,smaller than the others,grows to 8")Anything Grammastola,Brachypelma, and Avicularia would be a pretty good starter based on a few dealers
I talked to.
