If you've got a dozen events which require intercom, don't go cheap. Spend the money and get something good quality. My school has a wired Telex system which work[ed] amazingly. Unfortunately, someone from the county came in and started messing with things (there's a thread about it in the Punching Bag) and now the system won't work. We had to contact some people in the local parks and rec to borrow some of their wireless radios. I think they were more trouble than they were worth. Moral of the story. Buy something that won't fail you, and make sure its handled by people who know what they're doing.
