32 inch TV + only wireless internet connection, what's the cheapest way I can get quality programming?

Here's the deal, I just moved into a small room in San Francisco. My landlord doesn't offer cable, and I don't want to pay extra for it with my already high rent.

Being a poor college student/nerd in SF, I want to know my cheapest option for getting Netflix, and maybe (if cost permitted) a few other streaming services.

My landlord only offers a wireless connection.

I've been looking at the Roku's LT ($49) and Vizio's Co-Star ($99).

What do people recommend between these two and is there any better options?

p.s. I'm not too concerned about picture quality.
