i dont know where you live but i have a guy in texas i can recommend he fixed one of my switches from a preiviously failed install and modded my other he is really good i dont think it matters other than if you have an oled if you do have an oled you can use rp2040 picofl;y or nx instinct v6s these both work really well however i would research on if you want to use the kamikaze method of install or the regular adapter which slides under the emmumc for the dat 0 zero connection alot of people like the kamikaze method because it gives direct access to the dat 0 however if you dont know what you are doing it is easy to permanently damage your system as i said though my guy is really good he know how to use this method you can look him up on youtube he goes by wayayeo he aslo has a website that lists his number so you can call and setup your install remember though he only does hardware you will have to setup the software for your install the difference between the dat 0 adapter and kamikaze is that the dat 0 adapter has a high failure rate well the kamikaze when done correctly does not fail at all
