Keys for '70 Nova

[Gear_Jammer]

In my first post a while back saying I finally bought a '70 Nova, I mentioned that the ignition switch didn't lock, so you can start the car with or without a key. Several of you gave me some advice, so I called around to some local auto locksmiths and they all basically told me that in order to use my factory GM key, they would have to take apart a replacement ignition to make it fit my key and that it would be expensive. Since I would prefer not spending a ton of money and I don't want to have 3 different keys for my car, I was trolling online the other day and stubled upon this complete Nova lock kit - Ground Up . So my question now is whether any of you have used this setup, and if so, whether it's any good.

Thanks.
