Re: THL W8S
I've a ThL W7+ myself, which is currently about 130£. The GPS chipsets on the W7+ and W8S are the same, and it works like a charm for me. If you have a data connection, you automatically download some "Quick GPS Fix" data (it's an option in the GPS settings) that helps you get a fix in under a minute. For what it's worth, my Samsung Galaxy Ace had horrible GPS reception, as does my mum's S3. The reception on this phone is the best I've seen on an Android handset.
