I have an 85 UL in stainless finish and I love it. Trigger is smooth, it's very accurate and a pleasure to shoot. But I will say $300 for a used one seems high. I bought mine new at a show four years ago for $269 (before tax). Keep looking - you can find a better price.
Matter of fact, I just got an 856 UL in the black finish brand new for $319 (that was the sticker - I traded another gun, so it was less than that out of pocket).
