Congratulations! You'll really enjoy using the 7700!
I bought at wooden table at a thrift store for my machine. My DH cut out space for the machine, its plastic sewing surface and even cut out a hole for the knee lift. The table's legs are cut shorter for me (I'm short) and it's just right for me.
I've been getting used to using the knee lift, but I haven't used to start/stop sewing button. I love the machine and have a great dealer in Broomfield, a suburb of Denver.
