Anyone bought one of this range yet? I am wanting to calibrate my monitor. I am so confused which to go for. I set my mind on one, then i get talked out of it, i was looking firstly at the colourmonki display model. I need someone with experience to advise. I have a Dell u23 ips, i will be sending prints off for printing, would i be wasting my money on the elite, if i am only using it for monitor calibration.
