Best auto leveling air bag setup

[Nitrousbird]

My last truck ('07 Escalade EXT) had the auto-leveling suspension and I miss it.

 

I plan to level my SLT (Z71, probably 2" drop shackles and remove the block) but my boat is a bit nose heavy and will need some support as a result.  

 

I'm not playing with wireless controllers, apps, etc.  No reason for that BS as it should just do it on its own.

 

Who makes the best bang for the buck auto leveling airbag setup?  Christmas is around the corner and I'm sure the wife wants to know what I want...
