I have one but it's on my Duster, it's an Alston 10 point which has the two bars that go through the firewall into the engine compartment.
If you go with a cage get the swing out side bars, or have the side bars bent down, so you can get out easier. It will become a pain climbing over the bar all the time.
If your planning on drag racing it check the rule books on what is allowed with the side bars.
The only sucky thing with mine is that I can't open my glove box because of the front hoop, it may have been installer error. So just make sure whoever installs your cage knows you want to still be able to open the glove box.
