Thanks guys. For the record, I was ordering these movies from twistedanger.com, they carry a great selection of deluxe and compact bootlegs.
However I ended up going with Island of Death, The Evicots, and the Town that Dreaded Sundown.
To those who have not heard of House by the Lake, it is a Canadian rape/revenge film from 1977.
You can watch the trailer for it here:
