Bike seat post lock, is this device theft deterrent enough?

Yesterday I just had my seat and carbon post stolen from my trek road bike. The sad thing is that I was able to see the crime taking place on security footage. Anyway, I just purchased a new seat and carbon post, and it cost me around a good 150 dollars for a replacement. I was googling and stumbled on a website Saveyourseatlock.com, and they happen to make a bike seat post lock. I was wondering if anyone thinks that this is theft deterrent enough to keep this from happening again.

Here are a few pictures of the lock.

We use Pitlock in my household. It works and is much more elegant.

My saddles and posts aren't fancy. I take off any seatpost clamp that has a quick release and substitute one that uses an allen bolt. So far, so good.

If a crook is willing to take the time to use a allen wrench, he can simply remove your saddle from the post. Luckily, crooks, as a group are very lazy.

Pros:

1: It looks cool, a visual theft deterrent.
2: It will stop morons from yanking the seat out just to be annoying:

Cons:

1: The wafer tumbler lock is easily picked in the matter of 3 seconds or less.
2: It comes in limited sizes.

I like the product, but Pitlocks are a far better solution to this problem. Pitlocks have a far smaller attack profile, can't be easily "picked" with a paperclip (though not 100% secure), and protect not just the seat post, but both wheels and stem, without needing an additional key to carry around.

Looking at the design, here are my recommendations:

1: Ditch the wafer tumbler locks. Go with Medeco, and some type of cover over the cylinder. This will up the ante for picking the lock to accomplished locksmiths.

2: Make a similarly designed set of lockable skewers for the front and back wheels. Sell these and the seatpost lock as a set for around $50-60.

3: Consider making exposed parts out of a harder metal.

Now, this would be a package that would secure on the par with Pinheads, Pitlocks, and other locking skewers, and offer a LOT more different keys, as well as master keying, to allow bike rentals.

How about Sheldon Brown's method of using an old chain around the seat rails and the frame?

I have simply replaced the quick release seat clamp with a hex bolt one, and filled the hex key hole with Araldite. When I wanted to adjust the seatpost I drilled into the Araldite, entered a woodscrew and pulled it out easily. A thief would not likely have the necessary tools at hand.
I also use a black, tight-fitting rubber rain cover (Selle Italia?) over my Brooks Swift saddle when I park at work. You need to look really close to spot that it isn't a standard, black seat on that bike.
