I love my Tuttos. Just make sure you get the right size. I found the Serger case was perfect for my FW case. I can put my FW, my accessory case (i.e. holds extra bobbins, cleaning supplies, etc.), and even my Omnigrid case that holds my rotating mat, rotary cutter, and a small scissor. I can also fit in a small project if it's in a project bag.
I have the XL for my Janome 8900, but that is mainly to take it in for servicing. I still have to see which Tutto works best for my 301.
