I've got to wonder, what's the difference between the $25 & $115 ones?

The more expensive ones are usually self lighted and account for temperature, anti fog, better and larger scale. I have a $35 one and one I paid $125 for and I have to say, the more expensive one is nicer to work with but no more accurate than the cheaper one.
