I bought a Brian Leaske adjustable one, after I read early this year that the Turbo version was going to be available Real Soon Now, but I wanted one Right Now. It's actually very accessible with a Kokeln and no A/C, although that probably doesn't help much...
I see the digital one seems to still be "pre-order only", although I could have sworn that someone here said they fitted one, so maybe there's some beta versions.
