I have found the VA-5 to be an excellent choice. I have owned it for about 2 years.
True, the 3-button interface may not be the fastest way to change settings, but after experiencing an initial learning curve, I find myself remembering the menu structure and changing settings without much effort. That is true even when I have not used it for a few months.
Some would prefer an encoder - but there are downsides to a component with moving parts and a shaft which sticks up out of the device. The button arrangement makes for a smaller overall size, easily packed for travel without suffering damage. Touch screens are interesting gimmicks as well, but they are fraught with many practical issues.
Bottom line, I would say ¡®simple and durable is best¡¯, especially for a device which is often used in the field.
