Linux Enigma 2 receivers are a very great disappointment if you do not know linux and you are not so skilled in computer things. Also, these boxes are not for satellite enthusiasts.... no or poor blind scan, not so good for feed receptions.... and so on. Very good for multimedia and for computer playing. If you are a real satellite fan.... well, choose good old Technomate, Openbox Freesat V8, new Vuga/VIARK (multistream) or new little Octagon (hardware blind scan and Multistream without PLS). If you choose E2..... good luck.
Think about it : of all receivers you mentioned,and those you didn't,the only one that's been working through every change,every encryption,every stream,are Dreambox,meaning enigma 2 receivers.
Still today working as well as the first day,just go check those that has been in the market for the last 15 years,the only ones that still standing are dreamboxes.
New boxes show up in the market every month,disappear in couple years.
But the linux receivers are the ones that as all the features from the beginning,all of them,and all others tried to imitate,to the point they gave up and started making boxes that use enigma 2 firmware,and not their own.
And given the fact all other boxes use the public fixes from this forum,makes them all really inferior.
So,I am sorry you feel disappointed,but can not generalize your experience with the rest of the world.
Let's say this boxes are not for you.Maybe you just can't learn to use them.
At the same time,mines has been working since 2001 (from enigma 1) non stop,how could I (and countless others) be disappointed?
A real satellite fan? are you sure you want to start offending people by showing how little you understand about satellite and satellite receivers??
Please,go and take some time for reflection,I think you misunderstood the basics of the satellite hobby.
