I've got this one:

Yeah - its much the same either way. Personally I'd want something that has lifetime maps...traffic is less important but occasionally convenient ("left lane closed in 3.5km"). You can go for a TomTom...similar as I said...my uncle has a TomTom with a screen that looked washed out to me so i just stick with what I know.
Oh and don't change the default voice...default voice pronounces street names others don't. Sure it massacres the (Afrikaans) names but its better than "turn left".
Only thing I don't like about the 2495 is the cable...its too thick and has a separate lose cable / antenna thing for the traffic updates.
