Sat Nav at Costco

cheapaschips_2

I am thinking about investing an sat nav for the car and whilst in costco the other day spotted a navman icn610 sat nav system, their price was about £230 inc vat. having done a bit of checking around on gps sites and ebaythe gonig rate seems to be about £300 plus.
Is this a bargain?????
Anyone got any experience of navman of indeed the icn610?

Got a navman 520 from costco a few months back,£150 inc the vat and never had any probs with it occasionally a bit slow to pick up a gps fix,but generally does the job.Downloaded a speedcam database from a torrent site and installed that but not used it yet.The 520 does the job its supposed to ,the ony real prob being lack of full postcode,but if you know the exact address this makes up for it.
