I only had to solder one set of tape due to the way I wanted to loop the back low row and didn't find it a problem, you can buy kind of crimp connectors. I'm sure if you asked them to solder on both ends of a tape they would.
There is a some network version of the controllers but I couldn't work out how much you could really do over network so didn't bother. Not personally interested in away from home control but if I could get Alexa do do scenes or morning timed setups I might be. Trouble is that documentation is poor so basically you end up buying stuff and seeing what it does, you can return things however
