Make sure its a new one though!
Turnkey are owned by by Soundcontrol and Soundcontrol are awefull with stock (They dont keep any synths or expensive hardware in stock.) Whats on display is what they WILL sell you for full price if they can.
Turnkey are better since they are more web based it seems like everything dosent go strait out on display for anyone to jam with. But, when i got my machinedrum from Turnkey delivered to work imagine my disappointment when i opened the box to find no power lead and a machine with scratches and marks on.
I dont live anywhere near london and it took two days to get my new one.
Also search for the best price and make them beat it.
Be carefull they may try and rip you off!! :-o
