Even less than that around here. I've mentioned it before, but Hiwatt 4x12s are not particulatrly in demand locally - they're just a known-to-be-solidly-built 4x12, in a sea of similar options, though the port is somewhat unique from what I gather.
I think I'll put it up in the local adds as with or without speakers C$250/150, and take 100 unloaded if someone offers. Give the option of this weird set or the Marslands from my Riviera 4x12. I can easily get US$50 per pair for the speakers on ebay.
