I recently started annealing cases with the Ballistic Recreations setup that uses a Lee precision melter and potassium salts.  The entire setup cost less than $150 and it's simple to use and consistent.  I would have never considered annealing but my scoring partner at Talledega told me about it and I thought I'd give it a try.  The kit comes with a case holder made to fit the Lee melter, a thermocouple/temp gage and a jar of potassium salts.
