I found a nice leather case that is made for the 750/755. Here it is on the company (Fortte) web site:

If you search for the case on ebay, you can buy it from Fortte for $20 with free shipping - vs $25 plus shipping on Fortte's web site.

It is smaller than the standard case for the 700, so there is a nice snug fit. I like it.
