I had an Aspire and I liked it a lot but it was before they made a foot controller which I am very used to. I traded it in on a Shimpo Lite. It is a floor model whereas the Aspire is a table top model. The Lite is still easy enough to move around so you can take it to workshops and demonstrations etc.
Whatever you get, once you establish a new learning curve, you are going to be amazed at what you can do. Pretty exciting for me and everyone following you, to see you up the ante. WE watch with baited breath.
