Yeah I think it's normal too.
Have a listen to some when next we meet at the pony club Greg and see how they sound.
Monte's spot on about the EM200, can't hear it at all when tracking but when slewing it reminds me of a very quiet dentist's drill.
Ohhhhh, and leave the pour LX200 alone, I like the noise it makes, reminds me of an elec.coffee grinder.....mmmmm
