Pro Tools And Logic Pro 8, Some questions Options

[csoste]

Hi.
Since I have never used Pro Tools before I have some questions about it. First of all, does anyone know of a reputable website where I can buy the standard Pro Tools program that I have head of which costs approximately $1,000? I ask this because every time that I look up Pro Tools on webistes where it says that I can purchase it the only things that are available to buy are plugins or accessories for it, but never the actual Pro Tools software itself. Secondly, after I buy Pro Tools and since I don't have a full home studio set up yet, is there a mixer or other specific accessories that I should purchase along with it, which might allow me to make some broadcast quality recordings(i.e. recordings that can be played on the radio, put on the internet, placed in films or on televsion shows.). Thirdly, when one purchases Pro Tools is there a comprehensive guide or website devoted to teaching one how to use it?
Finally, has anyone out there used Logic Pro 8? How is it compared to Pro Tools? Is it better or worse? Should one purchase that instead of Pro Tools?
If someone out there could answer my questions I would really appreciate it.
Thanks.
All the best,
CSoste
