Are they gas assist? I wouldn't pay $250 for them missing parts and showing rust from sitting out, even though steel wool may take the surface rust off.
If your not in a big hurry, watch your Craigslist, I picked up a black, gas assist with a broken table for $25. It cleaned up real nice, got a new table, and looks good.
I understand you want a color, but like said above, you can swap the kettle later on.
I have a green gas assist performer also, I bought for $125...if the black one showed up first, I probably would never had spent the money on the green.
