You'd have to be
a) Fantastically Rich and
b) A Monumental Geek
to invest £3,500+ in buying a mellotron once owned by Rick Wakeman, especially considering that it only comes with six sounds (althought it does include the good ones - flutes so you can sound like the Beatles and choirs so you can sound like the end of the world). My recommendation: Buy G-Media's M-Tron for £33.99 instead. It's so good that even Liam from Toerag Studios says "It's OK".
