You should also report him for excessive postage. I noticed on the link you gave you could have had a new one for just £64 more with 12mth warrenty
http://cgi.ebay.co.uk/TACX-FLOW-CYCL...28713558463201 but only £5.99 postage using same parcel force so he stitched you up £19 on delivery too which ebay dont like.
