Stand-alone "box" Accutuner Verituner Single use machine, optimized for tuning.  Accutuner has been around a long time, is very sturdy and has a long battery life.  Spinning lights easy to see.  Steep learning curve with very limited display.  Verituner is more intuitive and takes in more information from the piano (especially useful when the custom style approach is used) Battery life longer than a laptop or pocket pc, but not as long as Accutuner.    2. Laptop computer: Reyburn Cybertuner Tunelab Pro   Large screen, adds the ability for massive storage, as well as having client data always available.  Reyburn has a very clear user interface, a great display and possibly the best pitch raise calculation. Tunelab's moving bars are easy to see and offers the possibility of rough tuning without using any mutes. Both have graphical representations of the tuning curve to assist with choosing an appropriate tuning style.  Each requires sampling of some notes to gather information about the piano before tuning.   3. Pocket PC Reyburn Cybertuner Tunelab Pro Verituner OnlyPure   The smallest, lightest option offers the ease of backup, data management and calendar options of the laptop in a smaller package.  Possiby more difficult to see and manipulate via the screen and stylus taps.   I've not seen the newest, OnlyPure in action, but recently there was a post with some tunings linked from Kent Swafford.   For the software, you will find people that like each platform and use them for the highest level tunings.  If you intend to be a "blended" tech - that is someone that works WITH a machine as a partner, how the interface works with you becomes important.  You want to let the machine do what it does best while also letting the ear and "wetware" do what it does best.    I personally prefer the Verituner at this point - I feel that because it takes more samples from the piano it offers a better chance at coming up with a more appropriate calculation based on what I want it to do.  I run it on a pocket pc - I like the ability to install it on a new pocket pc and be up and running without waiting for repairs in case it crashes... (or I run over it in the garage..... yes, I really did do that!)   Ron Koval Chicagoland <hr />Stay up to date on your PC, the Web, and your mobile phone with Windows Live. <a href='http://clk.atdmt.com/MRT/go/msnnkwxp1020093185mrt/direct/01/' target='_new'>See Now</a></body> </html>
