Tony - you're killing me!  You're aiding and abetting the draining of my bank account.  The books are the cheap part!  Now I have to go buy a grinder, a sausage funnel, casings , etc.  I figure that first sausage is gonna set me back about $450!  Of course, after that it's all marginal costing, but still .... 
Thanks for the pointers.  Those look like good starters for me.
