I'm the original poster in that thread.

I went with the DAS Sport roll-bar because it is the only "true" bolt-in option on the market. It does not require drilling any holes or the use of re-enforcement plates.

I spoke with owners of cars with the DAS Sport roll-bar as well as roll-bars from Safety Devices and AGI. The products from Safety Devices and AGI require drilling, enforcement plates, and more than one owner ended up welding it after the fact.
