can get an internet streaming device for my non hd tv

Just look for a Roku, Western Digital, or Asus OPlay style media player that does have the proper connections.

I'm assuming you're looking for something with Component, Composite, or S-Video outputs.

For example:

The $69 Roku has Composite outputs (red, white, yellow) for audio and video.
