CK 20 flexlok my first choice, or at least flex head.
I use a CK 20 series FL1525SF Flex lok gas cooled with a series 3 head and super flex hose 25ft
I too like at a glance knob settings of the 250EX is an upgrade from my Miller 250 Syncrowave

adjusted pedal stop
reduced spring pressure on pedal for better feel
added a heel clip to move arch of foot over the pedal pivot point
put some non slip feet on and widened base
works better than my stock Miller sdt

toothed belt wheel on pot slips on shaft, replace screws with short course sheet metal ones

More pedal
Like a pair of pants one size does not fit all.
As I am a fidler, I am always customizing my machines/controls to suit me.
All things have production compromises built in, sometimes just smoothing the edges of things can make a big difference in proformance or ease of operation.
Nowadays COST RULES. Both to the consumer and producer. Some times $'s and expectations get mixed up.
