I will check out the Kathrein range. I probably wouldn't want to spend more than €200 as my Vbox is doing the job just isn't the best tuner
What’s the main priority here. You mention the ability to create an m3u and a unit with four tuners. Personally I’d opt for a computer based solution rather than a STB solution. You do mention you wanted to avoid TVH but if money is a consideration it would be the cheapest route to go. Based on a budget of €200 the Kathrein range are not a runner
A stand-alone sat>ip unit is going to cost dearly. I always tried to avoid going that route until the Digibit Twin came along.
I really do advise you to go the Digibit R1 route while the seller still has them in stock. When they are gone that’s it. You’ll not get better for the price and the manufacturer has confirmed today that they won’t be producing them again.
