What machine(s) do you have now? What 3 features attract you to the F600 that you don't have?
I have the Juki F600 and love it so I may not be the one to talk you out of it. HA. I'm lusting after a mid-arm machine and need to be talked out of that (only because I need to put the money towards my daughter's wedding later this year). If I could just win the lottery. LOL
