My f/o this month has one and loves it. It looks nice, isn't heavy and the ANR powered by the ship is a BIG plus. I ran an ANR in the E120, but it had a battery pack, which was a pain. They seem a bit expensive, but he claims it works very well. Telex has been a good product for me, I have had a 5X5 with a molded earpiece for the last five years with no problems at all. Let us know how it works out. Where's the best price you've found for an 850?
