Helmet Headsets ...Can this be done cheaply?

[brobbed]

Hi all...
Being a new sei owner i'm looking for helmets for this spring. i was under the impression the headsets came with helmet. no such thing.
headsets w/mic are purchased separetly for a lot of stew.
Does anyone have an alternative to this big expense? or maybe recommand and new brand or website? i don't know much about this system, does the cb come into headset? and the music? and what about the intercom? any advice for buying used? %%-
