I love my 6600P - thought about getting a more involved machine and then didn't want to deal with the additional bells and whistles. But the 2 shops I go to will give you a full purchase price within 6 months at one shop and 12 months at the other.
Two years later I bought my Viking embroidery machine. Didn't want to trade in my Janome since I use both machines at the same time a lot of the time.
