eBay GPS, worth it or rubbish

[110county]

Gday All

Was looking at one of these units and was interested in other peoples thoughts about them.

or one of these

They seem very similar the latter one has promptly answered heaps of questions about the unit, runs windows CE and has an sd card slot so I could load any program and/or maps, is my understanding right? Intend to use mostly around the city and burbs then one day might get oziexplorer or whatever if I were doing a trip.
I am a bit wary of eBay things that seem too cheap they usually sell for about $300, am after something cheap but not rubbish.
Interested in thoughts and personal experiences with them, good, bad or ugly.
Cheers
Luke

I really don't know, never heard of them.
I use a Voxson Foxtrack, Brisbane company, made in Asian, works very well (used by most Taxi drivers in Brisbane) and has a pleasant english ladies voice

If you go over to the gps australia website, there is a bloke who has just purchased one and so far seems to be happy with it apart from no manual on how to use the route 66 software.
