ZEX Kit..?

I just had a few questions about the ZEX nitrous kit.. First I was wondering if anyone knew any place around Dallas Texas that would do it for a decent price. I was also wondering what all I would need with it. Does it come with the plate so I do not hve to drill into my intake? And if anyone has it or had it any suggestions or concerns. Basically what is everyones view on this kit. I have heard nothing but good things so far but it never hurts to ask a few more times.

I would only be running the 75 shot mayyyyybe 100 shot because it does have stock internals and rear end so I obviously cant do much more

Thanks everyone
