1. HUGE DIFFERANCE as far as ease. Still does not help keep the necks straight! 2. The best is the Wilson case trimmer with all the Sinclare add-ons. This is the best system I found without paying a lot of money, Like over 500.00 for the power system put out by the Pumpkin (who has the best neck turner ever made, also)I too have used a bunch of different equipment and find the Wilson to work as good as the best, its just slow as heck compared to Don's system. The file system, it vary hard to keep the necks square to the base, that's why the Wilson shines! Oh yea, The Pumpkin posts on this site.
