The times we've talked about this before, the general concensus (yeah,right) has been the value of electronic tuners have been great and an aid to ear tuning; very helpful in groups too. If you're working with autoharps, dulcimers and the like, they are so much more accurate and faster that I think "invaluable" is not too strong a word. Yes, the instrument should be in tune with itself, but as a help to getting more pleasure out of your instrument, as you have now done Peter, they're worth the few bucks you spend.
