For purists who want true uncompressed quality without relying on continuous internet access, purchasing the official complete series on DVD is highly recommended. These discs can be ripped into digital formats like MKV or MP4 using free tools like HandBrake to create your own high-quality digital archive.
Buy the German or Australian DVDs. Rip them yourself using MakeMKV (lossless). Then, use Handbrake to create your own "extra quality" MKV files (H.265, 480p, CRF 18). You will have the definitive, legal collection. If you cannot afford the OOP discs, consider this: write to Sony Pictures Home Entertainment.
