Anyone out there that owns one of these have any complaints?

I own a Lyman PDS and I am very pleased with it. It comes apart in a very unusual manner for cleaning. You need to follow directions carefully until you are used to doing it. Do not invert the scale to clean. No need to.

The scale is accurate quick and I like the cover over the pan to keep air currents from giving you false readings.

Just my opine.

I like mine for working with the larger stick powders.

Have had mine about 6 months, and it gets easier to use the more you use it. The neat little funnel/pan works great (unless I'm loading my .17), and my only major gripe is the 30 minute warmup.
And I agree, the powder dump is "unusual", but easy once you learn the steps.
