     I've found a potential alternative to the Allison setup for less than 
     half the cost of the Allison and wanted to know if anyone out there 
     has any experience or insights into relative strengths and weaknesses.
     
     The alternative is made by Pertronix(sp?) and utilizes a magnetic 
     pickup vs the Allison's optical pickup.  Purported advantage:  no 
     sensitivity to dirt.  Disadvantages: ??
     
     Also, the entire unit fits inside the distributor cap, replaces the 
     points and condensor (like Allison) and costs $49+S&H from Berret 
     Enterprises (818-967-5171)(posting only for completeness, have no 
     connections with these guys).  The Allison costs ~$120 and has an 
     external "brain" box (or so I'm told).
     
     My main concern is reliability of a "new" product.  If the Allison is 
     *bullet* proof, then I think I'd rather spend the extra $$ and get the 
     reliability.  So, just how sensitive to dirt (in a normally sealed 
     distributor cap) are the Allison units?
     
     Thanks again,
     
     Mike
