Which is the best way to go - internal or external system to protect the electronics in your rig?

Internal Pros:
-You will not forget the unit or have it walk off so you are always protected
-With a remote, you have a friendly display in your rig
-Many are repairable if they are fried
-Could be removed and mover to a new rig with some work

Internal Cons:
-A little harder to install, for some people I would recommend a tech
-If a surge fries it, you have to repair or uninstall it to hook power up
-Some of them have issues when running a generator and will shut down although there is no real problem

External Pros:
-Easiest to install
-If it is fried, simply unhook it and reconnect power
-Easier to keep and move to a new rig

External Cons:
-Easier to forget or have walk off if not secured
-Generally not repairable if fried
-Is out in the weather

Price seems fairly similar between both types.

I made the decision to go with an external EMS made by Progressive Industries. In a perfect world, I would carry two in case one got fried.

I believe an EMS is a high priority addition to your rig.

What have others done and why?
