Can I get some tips and advice when shopping around for a Galaxy S4?

[shadekeeper]

I am interested in buying a Galaxy S4 for Metro PCS

Hi everyone

I am new to the Galaxy line of phones. I am interested in buying a Galaxy S4 but since I have no clue what I am looking for, I sure could use some help.

I want to use it on the Metro PCS service.

Can anyone offer me any tips/advise while shopping around for one? I cannot afford a new one btw.

Thanks folks
