Saw this in the latest Woolies catalogue and thought it was worth a mention. I don't own one yet but will pick one up at this price point.
While not as quick as microwaving or stove-top steaming, it seems rather simple to set and forget until its timer goes off.
This unit gets a fairly good wrap by users on Product Review, stating it's simple, compact, and durable (some lasting over 10 years of use and still going).

you probably also retain more nutrients this way and cook more evenly, compared to microwaving
steam some frozen veg, serve with steamed rice and a salmon fillet or a can of tuna and you're done - a quick, cheap and healthy meal!
