Just bought from Richer Sounds - £99.95 with a further £10.00 off by becoming a VIP member (plus 99p for batteries to ensure I spent over £100 to get the £10 discount) - total cost £90.94.
Just to say really, if you enter the EXACT device number and spend some time tweaking its a really great unit (me and partner). Great support who can look at your setup since it is online. Cloured buttons is a strange omission but the touch screen does the job all be it rather too sensitive.
