Hey cwheat, I too am an EJ-200 Artist owner. I personally haven't had any fret buzz but the way I see it there are a few options.
1: You could try going up in string gauge. MIGHT help.
2: You could adjust the truss rod, but since there isn't buzz anywhere else, I wouldn't recommend it.
3: You could have the action raised a hair.
or 4: You could take it to a luthier for a set-up. Tell him/her that there is serious buzzing at 1 but none above it. It's most likely that the fret is uneven and he/she can definitely fix it. (I'd do this.)
I hope all is well soon. Cheers!
