Pro Tools Le Vs. Pro Tools Hd, The difference between both Options

[csoste]

Hi,
Since I have not used Pro Tools before and am looking to purchase it I have some questions that I hope someone can answer for me. First what is the most significant difference between Pro Tools HD and Pro Tools LE? Secondly, can one make Broadcast Quality recordings(Recordings that can be put on an album, played on the radio, or placed in films and tv shows.) with Pro Tools LE? If not, is there any recording software comparable to Pro Tools HD that is capable of making Braodcast Quality recordings, but that is a great deal less expensive? Thirdly, is Pro Tools LE compatible with Macs and if so, what device or accessories do I need to purchase to ensure that it is compatible with a Mac? Finally, my ultimate goals for this year are to build a Home Studio and to make or at least begin to make a home recorded album. Since this can't be fully completed until I have moved to a new house, what is the best and most affordable(For $1,000 or a little less) recording software that can begin the process? Many people that I've talked to have told me that a they use multiple recording programs when doing this kind of recording. For instance, they will record initially on Logic and then when they go to mix they will record in Pro Tools. So, which program is the best fit for one who wants to begin recording Master tracks that will eventually be put on album? Is Pro Tools LE sufficient or would Logic Pro be better?
If someone could answer my questions I would be really grateful.
Thanks.
All the best,
Charlie
