I really cannot buy any extra equipment or hardware for this. Right now, I can only afford to invest like $30 or $40 USD into this, and ideally, I would like this to be all in Bitcoin; buying any gear would wipe out any money for Bitcoin thereafter.
OK, if you want to get into Bitcoin now, can you afford to lose that $30-40? Why not start with a simple wallet and only $3-4 dollars, that way if you lose it no serious damage is done. As you gain in experience you will find things that seem horrendously complicated now become clearer.
