I got my springtail (tropical) from a local shop and one of the members from Dendraboard (temeperate variant), Seeing how I was going to wait awhile for some cb Pygmies I might acquire some more types of springtail (like giant kind which twice the size of pin head cricket, and the blue kind) to seed my terrarium and maybe to use a alternative food source should i pop out some baby pygmies.
As for isopods I picked up some white dwarf isopods from doubleds.org and got some orange isopods as a bonus (went to his place and picked up my order). I am planning to pick up 2 cultures of common stripe isopods (this guys are just a bit larger than the white isopods and supposedly more active) and jungle isopods (smaller than white dwarf) from another member of the dendraboard for clean up duty and snack item for the pygmies
