What do you think is the best supermarket instant coffee?

I like the Robert Timms individual sachets, you brew them like a teabag. But they're quite pricey, and i'm not sure they're worth it taste wise.
Mmmm yes worth it! I used to take them with me when I freelanced and it was too bulky to take a plunger and ground coffee Always had spares in my handbag!
