I've been chatting with John at Anatek and he is going to edit that page to show that the DS ESR kit is NOT discontinued. We shall be carrying his ESR Meter protection kits as well as some of our own ideas.
John :-#)# PS, the ESR kits have been shipped from DS in Australia, should be at the shop any day and we shall ship all backorders ASAP! The LOPT/Flyback kits are on backorder at DS though, sorry!
