Depends. With Firetide you have to pay extra for the 2nd radio and MIMO so when building a true mesh with outdoor radios you're looking at around $5000k list, not including the management software licenses which are required to install, commission and manage the network.
Expect to see from 25-35% off list for the typical sized project.
What cmaengdewd said is very true. Don't expect much tech support from them, not because they won't help you but because they don't seem to have too many people that know their own product:( On one occasion we had to do a demo with them and it was sad to see how they struggled to get anything going.
