Hi Don. The only monitors I would contemplate would be the AER's But, they are hellishly expensive too. Think I will stick to my little Ears!! At least that way, I'm in complete control of what I'm hearing! (depending on the competence of the Monitor/FOH engineer. I picked up my Trantec system for less than 300 pounds sterling off E Bay, and the ear inserts were about 100 pounds, (I think) A price worth paying IMHO for the peace of mind that they bring!!!!
