Learning To Fly?

Hi All,

Firstly apologise if this is not the correct group to post to (My first time
;0)

I'm thinking about taking up flying and have found a few schools in the US
that seem quite resonable (for price and facilities). They offer several
courses - i've narrowed it down to two: 'PPL Private Pilot License' and
'CAA/JAA Private Pilot License'. Can someone tell me what the difference
between the two types of license is? I've had a good rake around and can't
seem to find anything!

I would like to at some point get a night and IMC rating so with this is
mind does anyone have any suggestions on what I should go for (license
wise)?

Lastly, there are several aircraft to choose from on each course: Cessna
152, Cessna 172 and Piper PA28. Does anyone have any recommendations for
choosing an aircraft for learning to fly in?

Regards,

John.
