I have the Arrow Bertha and it works very well for me. It does have a nice work area to the left of the machine and also a section that opens out to the back of the machine, in addition to an open area to the right. With the lift for the machine and custom insert, I have a nice flat area for piecing and FMQ with my Pfaff. I have a relatively small area to use in my guest room and it folds up nicely when company comes. I bought mine on line and it was delivered direct from the factory (a USA company, which I like). My husband set it up, I would not have been able to do that by myself. I can't compare to the Wallaby because I'm not familiar with it. I know that Arrow fit my price range and it works for me. Plus has storage on the insides of both doors which I have filled with "stuff".
