Rice Cooker Help

My Oster rice cooker seems to have a permanent bollix. I plug it in and it
beeps and the display lights, but within a few minutes - whether I set the
timer and start cooking or not - it beeps again and switches off. At first I
could turn it back on, but now I have to unplug it for a while to reset it.

Naturally, this makes cooking in it unfeasible. So, I need a replacement. Does
anyone have a rice cooker/food steamer they recommend?
