After Gresham gave me a tip to try korean 'kimchi' vinegar instead of the regular Heinz or generic american stuff, I have to say I am really impressed.
I found some vinegar at my local korean grocery store (Kyo Po in Sunnyvale on El Camino). They have several different types. I was originally expecting large gallon+ sizes, but it appears that most of the vinegar comes in one or two quart plastic bottles. Unfortunately, most of the labeling was in Korean, which I can't read, but I did see some english labels noting that it was vinegar, that it was 'concentrated' and that it was 29-31%.
The store sold different types, some were in the $6 range per bottle and others in the $3 range per bottle. I discovered that the ones in the the $6 range seemed to be marked with 25% acidity and up. I am not sure if the cheaper ones are less acidic or just lesser known brands though. I purchased a white rice vinegar. They also carry other types. (Apple, etc.)
One of the bottles even said something along the lines of "DO NOT CONSUME UNDILUTED!". A little internet research indicated that regular american distilled white vinegar is typically 4-5% acetic acid. I am guessing then that this korean stuff at 30% is more than 6x the strength.
Of course being the skeptic I am, I decided to taste the korean vinegar straight. GAH! Very sour. Notably more so than the American stuff.
Haven't really used it yet, but will try it on my next powerhead bath.
