You mean the JD10 correct?
Check www.pedalgeek.com or you can order one from Award Sessions directly. Of course you can always check e-bay. They go for about $169 dollars U.S. or 109.95 in the UK and Europe.
I have two JD10's, the rarer JD20 and a GG10 Award Session unit. Offers would be seriously considered for the JD20 but, as there were only ever 100 manufactured by Stewart, it would need to be a serious offer. Based in France, though can be collected in UK when we're visiting next. Otherwise insured recorded delivery parcel post. Kind regards, Fairport.
