After shopping and researching online, I bought a Stanley Fat Max Mobile Workstation.
It has LOTS of room for everything I take with me.. and then some!
My Viking Rose, along with my 15x15" rotating mat and 16" square ruler will fit in the bottom compartment.
If I'd rather take my FW, the case and all fit in the bottom compartment.
The middle section has removable dividers for different configurations.
One of the larger items I store in this section is my iron and extension cords.
I also keep a ton of notions (bobbins/needles/pins/thread,etc)here as well.
The top section reminds me of a standard toolbox with a removable tray.
Again, LOTS of room!
