Interesting ! I have been using a Vibroplex Vibrokeyer for longer than I can remember, but now feel the need to try something else. I can now copy 35 wpm but I can only send around 25 wpm comfortably, due to a physical dexterity limitation. In the last couple of years several friends have encouraged me to go Begali, and now I believe I will. I had already decided to go single-lever paddle, not iambic. I've been looking at the Begali website and wasn't sure which single lever paddle to buy. Now I am thinking I'd like to try the Sculpture Mono, mainly because of the magnetic-loading and aesthetics.
