Oregon Scientific ATC2K
Price: £69.95
Cheapest on test, but the 2K is not without its compromises. The two AAs are not supplied, and while it’s sealed for waterproofing to three metres, the rubber switches take a lot of pressing to operate and the display is small. There’s no monitor, either. Still, although the VGA results were a bit jagged round the edges, at this price it’s very impressive.
