I've seen the Ikea machine and it is a cute little thing but I have no idea as to how it performs. I have a Brother CS6000i that I haul off to classes and such. It is very light - I can pick it up with one hand - and makes a decent 1/4" seam. I had to purchase the 1/4" foot but it comes with a walking foot and a free motion foot so that was nice. It was under $200. I have had it for about five years and used it exclusively the first 2-3 years I had it until I bought my Janome 7700.
If I had to judge the Ikea machine based on my experience with their other products I would say it is a good bet. I've had furniture and housewares that hold up beautifully.
