I got this D-05 sound module/Boutique synth from Roland UK as an ex-demonstration item. It is sold with a full one year manufacturer warranty. You'll be the first registered owner. 

The item is in excellent condition and will have be used for display or demonstration purposes.

Here's the link to the product description on the Roland website: 

I can also source all Roland and Boss products for you (including Boutique and Aira equipment) plus items from a full range of other brands including KORG, RODE, PRESONUS, GENELEC, CASIO and many others. Do get in touch if you have specific requests. 

My company, UCan Play, also has a range of other ex-demonstration equipment from Roland UK available for sale. Please check my other listings. A full ex-demo list is available here: http://www.ucanplay.org.uk/roland-ex-demonstration-stock/.
