I'm trying to make the decision myself... let me make it a little harder for you 
You could always get a Itig200 for $525 with the 25% discount or get it off amazon for $580 (shipped, not sure how much everlast charges on shipping...) but no foot pedal with it...
OR
get a 185 micro for $637 with the 25% discount... but still no foot pedal.....
OR
spend the $900 with the 25% discount and get the 200DX
If you are going to spend the $150 for a foot pedal anyways..... well it's like spending $750 for the 200DX comparing apples to apples.... I'd probably go with the 200DX
Everlast PowerTig 200DX
Everlast Supercut 50P
I need a MIG.... which one to buy:
I-Mig 160, I-Mig 200, or a MTS 160
