I've been a fan of Begali Keys since I purchased my first, the Sculpture, several years ago at the Dayton Hamvention. I'm not a super-fast morse op, and the cost is rather high, but once you use a Begali it's hard to go back to using other keys. The quality just gives a much smoother ride and the ability to fine-tune the adjustments lets me find the optimal feel.
Here is my current lineup of Begali Keys. I use the Sculpture when I am at the home QTH. The Traveler Lite goes out with me on portable operations. And my latest addition, the Stradivarius, resides in my office for use on the remote setup.
