It's a not very good brandable name so £0 would be my appraisal, unless you develop it into a successful website, in which case the sky is the limit.
FYI, Estibot is useful for a lot of things, but not for domain appraisals, so I'd stay well clear of regging domains on the strength of Estibot's valuations:
Eg CoversDuvet.co.uk is appraised by Esibot at $10,000 but is currently unregistered (but feel free to take it!)
