@Nobodyman:
Hmm, really? Do you have a better alternative?
Why yes, yes I do my good sir: http://over-ti.me/ (Their subs aren't filled with "kisama-yatsu" and they release episodes usually three days before Turvay Nurphon).
Unfortunately a lot of earlier Sentai hasn't been subbed and a lot of recent Sentai only has "baka-san-tachi" subs. From head I think Nihon has Deka to Boukenger (excluding Magiranger) with no alternative.
Luckily though Go-Onger and Shinkenger have scrubbers (taking subs and making them better) and I know that Go-Ongers are complete, not too sure about Shinkenger. Megaranger is also getting the episdoes that are out scrubbed but at a slower rate.
Go-onger scrubs - Shinkenger - Megaranger - Magiranger
Then we have the other Sentai that have been subbed: Sun Vulcan & Gaoranger (GSF) - Liveman (GUIS) - Dairanger (HON & H-S)
And finally on-going fan-subs: Jetman & Zyuranger (GUIS) - Megaranger (TV-Nihon) - Carranger (Haro)
Torrents have no seeders? DDL them here: http://krdl.info/
Oh also Hurricaneger & Abaranger have HK subs, I've heard Hurricaneger's aren't too bad and I'm not quite sure about Aba, I don't have any links if you're interested but they shouldn't be too hard too find if you actually want them
I'm not 100% sure but unfortunately I think that may be all the completed seasons thus far, I know of some subbing groups in-progress of completing series' but non of them are even near finished, it's a real shame too.
So I think that might be it now for "anything better" if anyone finds anything else subbed or w/e I can add it to the list or make a better one if need be, I hope this helps some of you (Finding subs can be a bitch)
