Before purchasing anything new I often ask myself what that particular piece of kit will bring me that I don't already have. It is after all very easy to spend a lot of money in photography and not gain an awful lot, but the B&W ND110 truly adds another dimension to your photography in my view.
I put this item in the same creativity category as purchases like a Fisheye or Tilt/Shift lens for the power to adjust an image or bring a look which is near impossible to get from Photoshop without a huge amount of manipulation. The advantage here is that even if you have to buy the more expensive 77mm filter, it's still a whole lot cheaper than investing in a new lens which might not bring another dimension to your photography.
Yes, it's not the easiest piece of kit to work with, you have to set the shot up first before screwing it on, and yes you need to know how long an under/over or spot on exposure takes (I would recommend downloading an exposure table from the net and carrying it with you). It takes some practice to use effectively, but once you are comfortable with it you will want to shoot more and more with it.
All in all, a great purchase that will both evolve you as a photographer and add a new dimension to your photography that I guarantee will get you excited...
