Boy, oh boy, were these metallic repaints ever unpopular! Not sure why exactly, they look pretty good. They just seem to be the most common and unpopular versions of the given model. This one, like Unit - 00, can be had for around $20 at shows or online, if you are patient.
While one would expect that Unit - 01, being from the same series and manufacturer as the earlier reviewed Unit - 00, would be functionally identical, this figure can be a bit of a surprise. It seems not to have any part reuse, and is a completely unique sculpt. It doesn't even have similar articulation! It seems to be sculpted in a more 'cartoonish' style than the rather 'realistic' Unit - 00, as well.
Additionally, there are no overlapping accessories.
