Linkie?
I dimly remember some sort of hot lather machine being advertised on the telly back in the 70's or 80's. I thought it was a neat idea, but...
For a while in my 20's I used cake shaving soap, a cup, and a little frothing brush for the daily face scrape. Never did go the route of the straight edge razor though. They kind of scared me. Nowadays a dispo razor in the shower takes care of trimming the periphery of the beard.
IMHO the whole shaving cream industry is a bit of a scam. I get perfectly good results (albeit on a reduced playing field) if the stubble is softened by the shower, and then just ordinary bath or hand soap does the rest.
