i've been asked to look into these for a possible municipal project, and i know absolutely nothing about them. if anyone here knows about this stuff, please post here or PM me. i need to know which companies make these, for what uses, expenses, maintenance, everything.
if you can point me in the right direction as far as researching these, i would appreciate that as well.
thanks.
