I have a mid-size Tutto that I bought several years back for my Bernina 1030 - I love it.
It stays in my car (now with a Jem Gold in it) ready to transport for workshops, classes etc.
Snipforfun's suggestion is a good one - wait for a Joann's coupon to get one when it's not on sale.
There's a new mini Tutto out now for c. $50 - I'm still looking to find it discounted somewhere.
