[SML] Wireless microphones

[Johnson, Philip]

Sorry if this has been asked before,

What are people's experiences with the lifetime of wireless microphone systems?

We use ours once or twice a year but the students are really hard on them.  The system is 8 to 10 years old and I have connector issues and also narrowing frequencies due to hdtv. 
It's and Audio Technica system with antenna combiner and 24 3000/5000 series units.  

It's feeling it's age.  Suggestions for new?   I see lots of system from the touring shows,  what is holding up the best?

Since we only use it once or twice a year, rental?  Purchase?  I worry about wear and tear on rental mics and having to replace them because of carelessness 

Need about 20 or so for our shows. 

Thanks for you advice
