For Christmas my girlfriend bought me a copy of Barry Thornton's "The Edge of Darkness". I'm quite enjoying it. I've used Dixactol in the past, but I wasn't very clear at the time, what I was looking for. I'm thinking that I may try it again. I seem to remember that, even from the Formulary, it was a bit expensive for the total working solution you got from the concentrate, compared to say,...PMK or Pyrocat.
My experience with DiXactol (used it for a year) was that if you are not very careful, you will get very flat negatives. The chemistry in DiXactol is not unlike the chemistry in Pyrocat. DiXactol will give you a little less grain. The formula is floating around if you wanted to make it yourself.
Here is the page on the Formulary's site providing complete instructions for using Dixactol. www.photoformulary.com/uploads/dixactol.doc As Barry mentions in his book, he also feels that Perceptol is one of the best alternatives to Dixactol.
