This is legit. No pirate/bootleg copy!
Time Life has released a 40 disk DVD box set of Power Rangers of ALL the episodes from the first season of Mighty Morphin Power Rangers all the way through Power Rangers Lost Galaxy! Plus it has extras on a bonus volume! These "classic" Power Rangers seasons previously had only been officially available on European (PAL / Region 2) DVDs, but for the first time they are now available in the US (NTSC /Region 1).

It costs only $219.95
This is for EIGHT WHOLE VOLUMES (7 seasons + 1 bonus features volume).
Considering Star Trek: Voyager (which lasts 7 seasons) cost $700 ($100 per season), I can tell you that getting 8 volumes for just under $220 is a HUGE BARGAIN!!!!!!!!!
