Any knowledge / insight / info on DMP panels?

Hi,

I had a dealer come by the house today and try to extoll the virtues of a 
DMP system.  I'll be honest; I've never heard of DMP before.  I've heard
and 
worked with Napco, DSC and even Paradox, but DMP is a new one to me.  So I

tried to do a little research, but I find information for DMP is not 
necessarily easy to find from anywhere other than DMP itself.

Is there a reason for this?  Is DMP considered a "good" alarm to have?  If

ever I decide to switch monitoring companies, is DMP commonly sup****ted,
or 
might it be difficult for me to find?  The dealer told me that they have
an 
exclusivity to distribute DMP in the local market.  Additionally,
searching 
for parts and/or components online yielded very few hits; I can't seem to 
find anybody selling DMP parts.  Is this not a popular system, or is this 
simply not as much of a  DIY-style panel?

Thanks for any info!

Eric
