Two monitors hooked up to one Macbook... How?

I have one monitor connected from monitor to HDMI to thunder port into my Macbook.

The other I have monitor to HDMI... but am unsure on the best/least expensive way to connect. I have a HDMI to VGA which I suppose could buy female VGA to USB... but is there a better way?

The other available port is a small "flux capacitor" looking port located as the 3rd port between power supply and thunder port.

I would like each monitor to behave independently, meaning I am not looking to duplicate the same working image on both screens.

Starrysky: I Googled it but didn't get the most simplistic answers. I found products that seem like they will do but cost around $80. My mistake I actually have one monitor that uses VGA to thunderbolt, not HDMI. The other is indeed HDMI to thunderbolt. I looked up the unnamed port and it is the Firewire port.

Duncan: Yeah I saw that the newer models can accommodate this fairly easily. Mine is a Mid 2012 model.

Which Macbook? Many post 2012 models will support two monitors from the Thunderbolt ports....
