Can anyone tell me whether it's possible to connect two external DVI monitors to a 2012 macbook Air?

Ideally I'd like to do this through the thunderbolt connector.. is that possible? Are there any adapters out there with two dvi ports on?

Otherwise, can anyone recommend a decent USB3 -> DVI adapter?

I'm not watching any movies, this is just for work (programming) so maybe a USB -> DVI adapter would be ok.

Ideally I'd like to do this through the thunderbolt connector with an adapter to drive both displays, but otherwise can anyone recommend a decent USB3 -> DVI adapter is acceptable if it's equal to or better than what I would get via thunderbolt.

I'm not watching movies or gaming on the displays, as this is just for work which consists primarily of programming so maybe a USB -> DVI adapter would be acceptable as well.
