I see one or two carts on YHJ at least once a month. seems to be a pretty average availability. I wouldn't throw money at a copy. wait till one pops up in your price range. IF someone wants to money fight over a copy don't get into it with them, just let them over pay for their copy and wait for the next one. I't will be cheaper next auction. $140-$180 is about the medium of what i have seen. anything more or less is an outlier.
FOMO is the devil.
