Something worth having, like television? (5)
I believe the answer is:
asset
'something worth having' is the definition.
(I've seen this before)
'like television?' is the wordplay.
'like' becomes 'as'.
'television?' becomes 'set' (television is a kind of set).
'as'+'set'='ASSET'
(Other definitions for asset that I've seen before include "Strong point" , "Anything considered valuable" , "good point" , "Item of value or advantage" , "Advantage, strength" .)
