I want to buy a Sat Nav. Which is the best and cheapest?

-I have just passed my driving test and I already own a car. I would like a sat nav as I am about to move. Which is the best and cheapest for me?We needed sat navs for 2 of our vehicles and being unable to decide bought one each of the basic Tom-Tom and Garman. Cant honestly choose much between them, Garman does not give speed whilst navigating and Tom-Tom sound quality is better, windscreen sucker and fittings are better quality on Garman.

However T/T internet backup much better with lots of e-mails with cut-price updates etc. Updates on G/m much dearer.

Hope that helpfull, but bear in mind I am at the 'bargain basement' end of the market.
TomTom One XL it's cheap big screen and very good. I think you can snap them up on ebay or gumtree for around 拢40/拢60.
Buy a Road Map Less Trouble. 拢1.99.
Tom tom are good and you can get some cheap ones online. Garmin are good aswell. Remember that all sat navs need constant updating to avoid accidents
