Dolphin Music have a Korg MS-20 B Stock currently at £419. It retails at £499 and most other retailers have their B-stocks over £450.
If you wanted to get your hands on the new MS-20 Mini this is a great deal!
This is my first post so if this is the wrong section then I do apologise - I don't have access to post in the retail section. This is a b-stock model though so it does kind of fit here.
