Memorial is not cheap, unfortunately (8)
I believe the answer is:
cenotaph
'memorial' is the definition.
(cenotaph is a kind of memorial)
'not cheap unfortunately' is the wordplay.
'unfortunately' is an anagram indicator.
'not'+'cheap'='notcheap'
'notcheap' is an anagram of 'CENOTAPH'.
'is' acts as a link.
(Other definitions for cenotaph that I've seen before include "Monument to the war dead" , "Monument honouring the fallen" , "construction in Whitehall" , "War memorial" , "Monument honouring persons buried elsewhere" .)
