I didn't read through this entire thread, so maybe someone already mentioned the Peterson Strobe clip-on tuner.
At first I didn't like using this tuner because unlike most clip-ons that I have used that just have a red or green light to indicate if you're dead on or not, this has a couple of bars that go side to side. To get the note in pitch you get the moving bars to stay idle in the middle, as much as possible.
I like the large clip on this tuner. It's easy to get it on square. My 10-string doesn't respond to my Intellitouch very well, but the Peterson has no problem registering a note immediately. And to my ears this is the most accurate tuner I have used.
Here's a picture.
