I'm building a new electronics bench in an 8x8 feet area, that currently has two outlets. I'm pulling one outlet and replacing it with a blank cover, 90 degree into armored cable up to my bench. This will go to a dual switch. One switch will turn on the overheat light and the other will power my bench outlet lines. I'm using 1 - 5' 10 outlet plug mold strips on each side of my L shaped bench. I have a separate 15 A feed to this location, so I don't expect loading issues. My electronics bench will be pretty low power.
With this setup, I will have a way to hit both switches down and assure that I'm completely dead to the bench, so I didn't have to worry about forgetting my soldering iron, etc. While I don't expect to be in a situation requiring an emergency kill, it will allow that as well.
Does anyone have a recommendation for a module I can put in this setup to have wired in surge/transient suppression? I'm finding things like this: http://www.amazon.com/Ditek-120HW-Parallel-Power-Protector/dp/B001UKKSV0 (http://www.amazon.com/Ditek-120HW-Parallel-Power-Protector/dp/B001UKKSV0) But I wanted to get advice if anyone has practical experience with putting one of these in.

Just some thoughts. Surge suppressors, even the whole line or whole home variants, are like fuses and not resettable. If they are faced with small surges over time, eventually they will fail, so its best to be able to replace them easily and quickly, as plug in modules rather than hard wired; alas such types are far more expensive than simple plug-in-the-wall types simply because plug-in-the-wall types are more in demand, and offer the same level of protection. Thus, its not practical to have a branch circuit SPD albeit its offered for sale [not to mention the installation costs]. For total protection, a distribution box SPD is a better option for taking transients from the grid [ if its modular], but in-home generated transients or those coupled to the home wiring by lightning or similar events, the last level of protection is still the wall plug in protector to which your devices are plugged into.

The above is an example of a modular distribution box SPD with easily replaced modules; each module can protect a branch circuit or a whole floor, say in a building.

Using DIN rail-sized ELCB's can be expensive , but hell they last a long time .

That is what I'm seeing in searching. The expense part...
