Electronics guys... we have our plusses and minuses. With advent of digital everything, we're being phased out

I own both meters and they are identical as far as accuracy is concerned. The digitel one is more flexible but NOT more accurate.
Here's a quick rule-of-thumb for the air-compressor... If you find yourself wincing, jumping, shying away or another form of physical reaction to the noise, it's too loud. At my work, they make me take OSHA approved audio safety classes (but then I live in headphones).
I've got the digital meter from Radio Shack, and it works quite well. It does have peak level, and data hold. I went with digital mainly because easy peak level check. Some people may prefer the analog, but I think it's easier to read exactly what the number is on the digital. Maybe not more accurate in measuring, but for reading the output, its more accurate than following the jumping needle.
It's not very expensive, and well worth the investment.

The analog meter version is preferred because
1) it's just as accurate
2) it costs less.
Unless you absolutely need to look at digits or use peak hold, there is absolutely no reason to spend more. For judging loudness, you want a running average reading, and the analog one will actually give you a better idea of the range (you can more easily see where the needle spends more time in its swing)
I don't know where you got the claim that the digital one is more accurate, but the analog meter's accuracy is well known and proven. Even its slight nonlinearity at lower frequencies is well documented.
