Ive decided to get an X-Box..

I would like to have it chipped etc.. Whats the best way to do it ?

Should I buy one then get it chipped somewhere ?
Are they easy to chip, can I do it myself ? Ive chipped a few PSX and PS1 consoles in the past, so I have a bit of experience..

Is there anywhere doing them ready chipped ?

Any advice would be greatly appreciated

Kind Regards
Steve
