You don't see much about these any more but they really are getting to be a collector if they are a pre 64. Essentially they are just like the 88 in fit and form, but the 88 is a lever and the 100 is semi auto. They've gotten kind of a bad rap for reliability, but really the trick is to clean the gas system. You also have to get the new firing pin put in. Years of R&D went into them by the folks at Winchester. To me anything made pre 64 by Winchester is good. Like those old model 63 semi auto 22's. They sure don't make em like that any more. I am thinking about getting another 100, here is an example of what I am talking about: Lets here about your any nice 100's out there.
