Purchase of New Regulator for Carbing

I am looking to purchase a new regulator for carbing outside of the kegerator since there is not much space inside my three tap keezer. I have a 5# tank inside the keezer and just picked up a 20# for very cheap.

Right now I have a Taprite Dual Body regulator with 1 gas line coming off one regulator and a two way air distributor coming off of the other.

I am not sure what direction to go in with the next regulator. I don’t see myself carbing more then two at a time. I am interested in having the option (cost dependent) of tapping a sanke tap.

Any suggestions for a direction that I should go in?

I have an old regulator where the pressure creeps up. I have it connected to a paintball tank. I carb one keg until I have the next one ready. Never needed a splitter.
