A question for those of you who've used both of these machines: is the Horizon a big step up in terms of how complex it is to use? I have a Janome 4800 and have been considering a 6600 for some time. When the Horizon came out, I looked at it but it seemed so big and daunting that I've stayed with the 6600 as my dream machine. Now, seeing all the positive comments about the Horizon, I'm wondering if I should reconsider, especially given the bigger quilting area. Do you think it has a steeper learning curve than the 6600, or are they pretty similar in terms of set up and use for piecing and FMQ?
