Pretty good. Here in the UK, we've always got very elaborate hard shell cases styled vaguely on the show. TNG's sets are in silvery grey boxes that look like a tool box or something, with purple inside. DS9's are similar, although they're black (well, dark navy I think) with cardassian bumpy patterns all over them. Voyager's are similar to TNG but red with a white strip. They all have the actual discs inside smaller holders that unfold, with lots of artwork and images on them. They look really nice. TOS comes in similar hard shell cases but they literally split in half and the smaller insert rests in the middle of them. They're coloured yellow, blue and red, for the different seasons, and look amazing. Enterprise's box set are similar; they also split in half, but they're all silver colour with the blue inner boxes visible through the outer shell, like they're part of the warp core or something. I think these versions were released in the US as well, actually. They've stopped doing these ones now, though. The current issue of box sets are all slim cardboard packaging, which I suppose is more convenient for storing them, but not nearly as cool. I should take a photograph at some point. I've got the whole set of every series stacked up.
