Eversewn does have nice rolling cases:

I'm really tempted to get a Sparrow 30....just because of the happy comments here.

I found this rolling case at Amazon for $79...wonder if it would work:

When I bought my Janome I bought the Tutto - but that was so I could take the classes on how to use the Janome - I also use it for my Viking because they are both rather big. But for my little portable machine I bought a rolling case from Joann's with a coupon - I believe it was a 50% off and it was very inexpensive. It was such a good deal I went back about a week later and bought one for my sister. (It was on clearance and they still let me use the coupon since they said clearance is not sale. Okay!)

I have had my Sparrow 25 for almost a year and I love it. Stitch quality is great for a light machine. Now that I have put it through the paces, I wouldn't hesitate at all in getting the Sparrow 30 if I thought I really needed another machine. I "won" this machine in a contest. I have been pleasantly surprised at its performance. Try one out if you have a chance. There are some youtube videos on the Sparrow. Alex Anderson likes it as well as Leah Day now uses it to quilt her quilts and carries them on her website.

Eversewn has a tote. It may be available online, but I saw it at the shop where I bought my Sparrow 30.

I have a "tool" box from WalMart and my friend has one from Home Depot. The machine fits in the bottom and it has trays above that will hold your thread, rotary cutter, scissors, etc, etc. Much cheaper than the sewing stores and much more useable.
