Well a nice guy on the site is selling me his toplink for $40 including shipping. He said he switched his out for a larger one years ago and it has been just sitting collecting dust for several years now.
At least I'm not paying too much of a premium for it being gray that way. I kind of like the idea of having a toplink set for different pieces of equipment though.
I still don't understand why the OEM toplinks are so much more expensive. Most of the other parts don't seem that far out of line but I guess maybe they are.
