Walker posted some great info on PWM designs a while back. That's what I used and changed a few things around to have led indicator lights.

My 0.02. Hope it helps
The Auber PIDs with manual mode are actually easy to adjust. I don't have/use one myself, but in manual mode, the "percent" of total power is displayed on the Set Value window of the pid and the ^ and v keys adjust it.

But, yeah... a PWM with a knob is pretty cheap to build. I have a little red LED indicator on mine, too, but I just didn't include one in the schematic I drew and posted.
