Looking for Sonic Frontier SFM-160 mono blocks

Hi, I'm looking for sonic frontier sfm-160. Any sell?
You might check with Josh at recycledaudio.com, he is a AudioGon dealer. Also check with audioclassics.com.
if you are amenable to buying from Canada you could check with Partsconnexion who often have used SF pieces for sale, some of which have been upgraded but all are gone over so that they meet original factory specs.
I just worry about if they sound the same as original one with PartConnexion
