I contacted the case company today. Turns out Frank the owner, at my suggestion and using my specs put things in motion right after we talked Friday to make the Tyros 4 and 3 cases available as a regular production case to fill a need for some cases that we keyboard players would want in a quality case. I stressed the issues of weight, dimensions and of course a good price.

The parent company is apparently Hybrid Case Co. They have a number of divisions on ebay: islandcases, nycase, pockettrunks, casekits, etc.

They also have a division called Road Cases USA. I don't completely understand this marketing strategy, but I guess it works.

Here's another ad for these cases on Road Cases USA:

Here's a partial list of their clients:

Here is info on the lightweight luan plywood that is used:

I will be writing a review after my case arrives.
