I think it boils down to whether your primary orientation is live/jam or home-studio/finished-songwriting.

Teenage Engineering's stuff makes me imagine visceral live shows with lots of space for free form, improvised content-- up to & including a whole new growing subculture of kids being able to instantly make piping fresh, context appropriate art anywhere from the living room to the campfire.

Tweaking instruments and song parts iteratively over days & weeks to get an ideal finished product is really a whole different thing. The more big gear you can bring to that effort the better. I also second your advice on second-hand music equipment, most of my stuff over the years was acquired that way and it definitely gave me more opportunities than problems.
