This is a good deal. I contacted MSR and asked them what are the changes for the new model that has a green fly and brown tub. Here are the changes for the new one besides the colors are:
Same poles but the name on the poles has changed from Easton to MSR.
The side walls on the tub have been increased from 8" to 10" in height.
The floor coating has changed from 10,000mm to 3,000mm.
Also the weight has increased 4 ounces.
I have been searching for a while know and this is by far the best deal at $250.
