Picked this up off the US version of Amazon, and haven't regretted it. As various reviews across the Web imply, the "updated" special effects look fantastic, yet manage to remain quite true to the spirit of the original series. Similarly, these episodes HAVE NEVER LOOKED BETTER. They are not just scaled up version of the DVD version. I found myself showing off this show, just to demonstrate what the studios can do with a carefully treated filmstrip - even if its almost 40 years old. On a few occasions, you might see something a bit grainier, which DOES look like a blown up bit of DVD footage, but its rare - maybe 2-3 seconds of every 4th or 5th episode. I bought all three seasons, though the first one seemed to have been cleaned up just a bit better than the 2nd and 3rd... Of course, it may also be that the 1st set just has a better set of stories, making it more enjoyable. In any event, if you enjoy "old Trek", and haven't seen it cleaned up like this, this set certainly makes for a fine addition to anyone's collection.
