I wouldn't say Paradox is high end as I am having it now in my house. It is reasonably price but it lacks some nice to have faetures that I would like to have.  For example, there is no voice module to inform you when you arm and disarm your system; the GSM module is not stable; the standard configuration does not include Internet accessibility; the door opened chime volume in alarm off mode cannot be adjusted to louder volume, etc etc.  Of course mine is the standard configuration and not Magellan.

That said, it is quite reliable as it works as intended and I do not encounter any false alarm so far.
