If you need a drum machine for techno, this is the starting point. The Volca Sample II is a bit more flexible, the Drums are quite flexible but very difficult to define patches, this is what you need. With the Roland boutique, you have more options but they are three times more expensive!

Incredible drum machine, I have had it for a year and I am very satisfied, the only complaint is the sound of the snare, but you can adjust it and it sounds great. The price is unbelievable, I would buy it even if it was priced at 200 euros. I make hip hop beats, so I recommend it for anyone making hip hop music.
