They're all over eBay at a fraction of the cost of the R1 releases. But are they legit? I got a few to fill in the gaps in my collection, and they're definitely bootlegs. They contain all of the original content in English, but they're the typical Asian bootleg recode-a-roo wherein the contents of a double-layered DVD is reencoded to fit on a single-layered one. Playback looks okay, but by definition the legit ones look up to twice as good. Some might not mind, given the ridiculous pricing of all the Trek series box sets, but be aware.
