I have a Janome Gem that I actually bought at the same time as my 6600, simply because of the need for an extra machine and a free-arm. I have never regretted that decision. The free-arm is terrific, and it has a surprisingly strong motor. I don't sew garments much anymore, but I do make a fair number of bags, and the free-arm comes in handy, and sews through many layers without a problem. I've even done some fmq on it and it worked great.
