Looking for or avoiding is pretty much a preference thing I guess, since I have not used or seen many aftermarket kits.
I can tell you it's a bit of a challenge finding a good spot for the servo's, and they seem to have plenty of oomph for moving the lock rods and everything.
The best way I could find on the dart was to put them parallel to the lock rods about mid/rear door.
I did extend the wires for the drivers side to route them the way I wanted, and it was a bit of a decision to punch and drill for the door to body harness.
I used tubing from the body to the doors that seals and contains the wires.
Also the kit I got was actually for a four door, so I have two extra slave servos and it came with two remote fobs with batteries.
This is the one.
