I agree with all the statements.... Get the one you want, for everything you have done for everyone else you deserve a nice treat. I had the same dilemma when I bought my new machine in January.
It would'nt hurt to take a look at the Juki f600 either.....

It has almost all the bells and whistles of the higher end machines without the price tag. I played on a Viking 960Q and a 580 Bernina before I went with the Juki; it is quitier then either of them and I prefer the way it feels most of all.
Just wanted to give you a different lower price option that you may not have known about. If I guessed your location well enough, it looks like there are a few dealers in your area. (Sorry to be stalker-y)
