vern juenke quit making those this last year as he finally retired.
your best bet is to post on BR central in the 1 K forum also and see if anyone has one. Saw one sell in the last year. Expect to pay $850 or so for used one.
Supposedly someone is trying to come out with a similar machine.
FYI a Juenke machine measures deviations in bullets and cases. It spins the bullets and cases and has dial gauge that shows "deviation units". Top 1K shooters sort bullets by 1-3 DU groups and cases similarly.
You are not the only one looking. anything under $850 is a steal also.
Have not heard the details of the new machine that was supposed to being developed, but thought someone was trying to improve on what Vern did with a more current version that would not infringe his copyright.
Also heard that someone has been talking to him about buying the rights to the Juenke and starting production back up.
