Giant GSR FS Opinion and advice wanted

[Pete]

Hi, Anybody had any experience with the Giant GSR FS or with Giant bikes in general

Just looking for a regular commuter with enough sustenance to survive the tough city streets;
nothing fancy.

What's the "sweet spot" pricewise for a general commuting MB.

My budget approx £150; just looking for suggestions and which brands to find/avoid.

Any tips out there from the pros?

Thanks in advance
