I have one, I like it. The amperage setting on them is a bit odd, mostly because it does not update the amperage on the display when using the foot pedal. Download a manual and read it. Also look through some posts about the 200DX. There is a new version that is currently available in Canada, and I believe soon to be available stateside that has a more conventional operation to it.

I run mine on a 30Amp dryer circuit with 100+ feet of 10 gauge extension cord. Full power on AC and haven't tripped a breaker yet.

As for teh discount, you will have to qualify for the contest to receive it. 100 posts required from your starting count until the end of the contest. I have never used a coupon from the contests. I believe I even still have a 40% off "coupon" from one of the original contests, along with a 25% off one.
