I have a Janome 6600P. It's a great machine with a very nice stitch and a larger throat (harp- the space to the riht of the needle). I like that it has the built in walking foot and does a very nice FMQing stitch.
If I were to buy a second machine I would get a Juki 2010 to start a little collection going.
I also have an older Elna 6300, but that's at my Moms house indefinitely for her to use. She wanted to "buy" it from me, but I decided an indefinte loan is better. I can't take money from my Mom...
