I have a pair from a few years ago - part of a jacket/pants combo. Can't remember what I paid, but unless you find a super close out, you're going to spend $100-$200 for a decent pair of pants.
Used to be harder to find high-tech non-insulated skiwear. You have more choices now, but these are an "OK" deal for what you get. They are reasonably waterproof and unless it's really raining (as opposed to a steady drizzle) you'll stay dry. The zippers are not state-of-the-art waterproof and there is a rear "zip around" flap from one leg to the other which gives you a flap for droppin trou. It goes up both sides of the leg and just over your buns when seated. You may or may not like that - it makes the fabric a little stiff when it needs to fold, but not uncomfortable. The zipper is not in a location that will wick water off of a chair seat. The fabric is heavier and stiffer, not the softer stuff that is in vogue now. What you gain from the fabric is resistance to wear.
They seem to be sturdy and well made, but I really haven't worn them enough to tell you how many days you'll get out of them. I probably have 20-30 days in them in 3-4 years and they're still like new. I don't wear them when it's raining, but they're great on a "normal" day when temps are 0-30.
As you push above $200 you start getting into the range of some more advanced waterproof/breathable gear. Another $100+ and you are in sale range of some top-end stuff. Really depends on the conditions you're going to ski - i.e. rain or back country. The TNF's are a great "woods" pant because the material is tear resistant, but they lack the waterproof performance of the highest tech stuff available now. For typical "resort" skiing -meaning in bounds - the TNF's will work well for you. Then it's just a question of are you happy with what you're getting for $200 compared with what else you're seeing for the same money. If you don't need the abrasion resistance, you could probably find another pant for $100 - $150.
TNF isn't cool anymore, so as long as snickers from the peanut gallery don't bother you, you'll be fine. The gallery is kinda funny - they eschew fashion at all cost, yet won't be caught dead in the wrong thing. Go figure?
