I was so fortunate to be able to get a used Koala from a lady who no longer was able to sew. It's the big one with all the extensions. It's an older model but still like new. Has the lift for the machine. The price I've seen on ads for this one is over 1200.00 and I got this one (thanks to my sweet daughter who bought it for me) for $450.00 I love it. It's so well made and solid so no bouncing when sewing. The only thing I had to buy was the insert for my Viking.
