Wholesale prices are usually $200+ but this one is pronounceable and also passes the radio test (sort of) so it's will get a higher price than random LLLL.com's.
End-user: It all depends on what the end-user is willing to pay, several TLD's are developed so there are many potential buyers out there. I would ask for low 5 figures but might settle at mid $xxxx..
Edit: Didn't even notice that this LLLL has a word (SO) and an 'acronym' (EZ) .. great LLLL imo.
