You did not say what size you have?
I will be watching this thread closely, hoping I learn from it. I recently finished building up my Nomad size 590M.
Before I ordered the frame, I could not get a firm answer from SJS on what type of case or container the bike would fit in, but I concluded that if I traveled with the bike I would be willing to carry the fork in a separate duffel bag. Thus, I asked a very specific question - whether or not the bike would fit in an S&S type case without the fork and was told yes it would. I have a soft duffel I often use for airline travel that is longer than the fork, so carrying the fork separately is not a problem for me.
I also do not plan to carry the fenders and kickstand if I take it on airline travel, these items would stay at home. I am undecided if I will use pipe insulation for the frame or if I will wrap it with that perforated rubber sheeting that some people buy to put on their kitchen shelving. I bought some of that sheeting at the dollar store, I might use that instead, would likely use velcro straps to hold that on.
After reading this page on Co-Motion website, I decided that I would rather buy a soft case like the S&S backpack rather than the hard S&S case, in part because if I must I could fold up that backpack and carry the backpack on the bike.

While carrying the backpack on the bike is not an ideal solution, it may open up some options if I need to put the bike together in a location where I can't ship or store the case.
If I order the S&S backpack in USA, it appears that Niagara has the best price.

I might still do that, although leaning towards the backpack. If I get the cardboard box, my only option is to buy 10 of them, but if I do that it is still the lowest cost option.

I know that I will need to be careful to keep the weight below 50 pounds, I have a tiny little luggage scale that I would also use.
Sorry that the best I can do is not give you a firm answer, but I have told you what I know here. What size do you have?
