Do you like Baboon spiders in particular or do you just like the M.Balfouri especially?
You could always start by getting yourself some other more affordable old world species or Baboon's like:
Heteroscorda Maculata (Togo Starburst, Fast, gorgeous, arboreal)
Poecilotheria Regalis (Indian ornamental and other Pokies, gorgeous)
Psalmopeus Cambridgei (Entertaining)
Psalmopeus Irminia (Suntiger, fast, gorgeous)
Chilobrachy's huahini (Giant Asian Fawn, voracious appetite, heavy webber)
and much more... there must be something else you are interested in?
