I'd wait a while after its released before considering buying, give the You Tube videos on how to get it to work as advertised a chance to be uploaded.
As always Lee have great ideas but often drop short in their execution, look at their new hand primer.
Interesting how Richard Lee's son is overturning all the old Lee thinking. Cast iron presses, ergo prime, new trimmer no recent record holding claims for their dies either, revamped mould designs.
I hope it works well but I'll wait and see first.
