what are some machines available that folks are familiar with? I know that everybody is going to fingered extensions and I know that I'm a black sheep for liking the machines, but that's just how it is. I've always had the old clunky Horst machines and now I may have to get another kind. I don't like the fingered ones (especially for my big string length) so I'd only like to hear about keyed machines at this time. Any suggestions (other than to buy a fingered)?
