it feels like ages since i did a post on a great kitchen tool; but love this collapsible colander i found at momastore.org. an award-winning, design which was inspired by the expandable sun shield of an old camera. $65
or this one from solutions.com. price $14.95
they store flat in a drawer when not in use. pasta won't stick to the silicone surface; heat resistant to 500°F and dishwasher safe.
