The ONE 3rd Edition adds an excellent safety feature to an already outstanding unit, though it's a shame battery life hasn't been improved. Regardless, it's definitely great value at this price.

The latest edition ONE features an even smaller design and an EasyPort mount, and supports TomTom’s Map Share feature. The ONE continues to set the standard for other GPS units to strive for.

The S30 is an ideal GPS unit for those on a budget. The entry level unit combines a stylish design with good maps, a reasonable feature set and a very competitive price.

Laser’s Navig8r M35 is one of the best value for money GPS units we've come across. Don’t let its low price fool you: it is packed with features, including detailed mapping data and Australian-accented text-to-speech.

The nuvi 250 is a solid unit and commands a lower price than the 250W, despite possessing the same features.

The C220 is a solid choice if you're after an entry-level GPS unit. Excellent maps, speedy performance and a competitive price may be enough to overlook the sometimes confusing interface.

As an entry-level unit the Moov 300 is a solid GPS device and an ideal choice if you happen to be on a budget. It may lack the bells and whistles of its more expensive counterparts, but it nonetheless provides a reasonable navigational experience.

The EVO is a welcome driving companion and, although not perfect, works well for providing early warning of safety hazards.

Navigon’s 2110max is a reasonably low priced GPS, but the lack of text-to-speech and Bluetooth capabilities may be a deal breaker for some.

Though a relatively cheap price point is sure to entice, several gaps in functionality make the GPSMAP 76 somewhat undesirable. It is functional if PC connectivity isn’t paramount, but for the most part it's worth paying more for the extra features.

Costing the same as a low-end automotive GPS unit, the Triton 200 forgoes a touch screen as well as turn-by-turn and voice navigation in order to specialise in detailed mapping for outdoor activities. However, without the expandable memory required for detailed maps, the Triton 200 doesn’t provide the functionality necessary for more complex hiking and geocaching adventures.

Although the GPS 60 looks like it means business, it doesn’t live up to expectations. A USB connection and Garmin’s MapSource software are small consolation for the lack of mapping and slow signal acquisition. There are better — and cheaper — handheld GPS options.
