Mellotronists

Hi to everyone- I am a seventeen year old female called Gia, and I am 
a fairly new mellotron fanatic- Ever since I fell in love with the 
Moody Blues about 2 years ago, I also fell hopelessly in love with 
the mellotron! I haven't got a CLUE about any of the technicalities 
and I am FAR from a mellotron buff, but i love the mellotron sound 
and i feel a deep affection for the clunky old machines!The thing is 
the best mellotron I have EVER heard is the atmospheric, wailing 
mellotron that the moody blues used- it sounds like a creepy, thin, 
synthetic orchestra...... can anyone tell me EXACTLY what make and 
model the moodies used, so that i can go about getting one for 
myself?...... thanks!
