Help Wanted

Hi typosphere!

So eventually, I'll do a post about one of my grail machines that I finally acquired, but today, it's another question. I'm not looking to buy another machine right now, but for future reference, what are everyone's opinions on machines that can keep up with excessively speedy typing. I'm 70-80 WPM on a computer, and can probably get close to 50 on a typewriter... but the problem is that, at least with my SM-3, every time that I start to speed up, we run into the same old jamming problems that comes with lots of typebars flying in an enclosed space. So, typospherians, what are your favorite machines for speedy typing?

Once a scientist...

You know you are always a scientist when you have an idea and the first thing you reach for are a Sharpie and a paper towel.
