I now have an intellitouch tuner with the back lite option. I haven't used it on the job yet but in the living room it seems fine.
I now have four tuners. 2 korgs ( One very old and one not so old, but still old), a Dijitech II, and the Intellitouch.

The all do the job well enough for me to be pleased with them. The Intell seems to work best and fastest if you strike a harmonic on the 12th fret.

No complaints on any of these.
