I got a cheap pair of the older style ones about two years ago (something like $50 discontinued at Sierra Trading Post). I have used them maybe 100 times as felts, felts plus studs, and lugs. They have worked fine and the tops and bottoms look like new. The one issue is the old velcro closure system is starting to give some problems. They pack with mud or snow and start letting go. They also catch lines at times. These problems seems to have been addressed in the new designs. I would likely do them again except if you are not allowed to use felts anymore you might as well get boots with lugs.
