I bought 2 machines this summer and got to play with the 301-A yesterday. The cabinet is one that I haven't see before. The left side panel had hinges I could see on the outside and there was a "box" on the inside mounted. I pulled on the left panel and it swings out and you and you can store things in it. Also the knee/footcontrol is mounted in the front. Others I have seen have been mounted on the right side. I am hoping to be able to add a picture with this. Well guess I need to try the picture procedure again after reading more.
