I have a Koala, and for the price I paid for it, you'd think they could have provided more than two measly drawers in the thing. It has a flip up back for support when you are quilting a large quilt, but where they placed the lifter for the machine is all wrong, and less than half of the flip up back can be used to hold the quilt if you keep the machine on the lifter! If I had it to do again, I would do as 'All Thumbs' suggested and buy two sturdy church like long tables, put them back to back and then buy a small cabinet to go under for all the things you need when you sew, like needles, pins, scissors etc,etc, etc. When you're not quilting, you can place your machine, and your serger on the table side by side and really go to town!
Koala is only make of that fiber board stuff anyway. Not worth it.
