There is a used dynasty 200 dx for sale in my area. Asking $2000.

The serial # determines it to be an 04.
Miller Tech support says it has a clean history.
The owner claims it has low hours with a moonlight operation.

How long do these machines typically last?
What goes out?
Are there any things that Miller changed over the years?

Blue lightning came out in ~08. I've heard its nice but nothing to write home about.

I have experience with a new D350 and really like the ability to play with wave frequency on aluminum.

Thanks for the help!
