Keep checking here and DVD Forums, ex-dem.co.uk, hififorsale.com, Loot.com and the usual other suspects. Put wanted ads on each (where you're not banned ! ). You will get one as people move onto the 875 and such. I'll keep me peepers open for you too.
Sorry it didn't work out with mine (public apology but 'tis a long story and I'm just about to move house with everything boxed up and mess everywhere). Bad timing on my part in offering it up for sale at the moment.
