Nitrous Guys...Which Bottle Opener do you think is the Best?

Well....there are a few choices out there...You have NOS, N/X, Zex, Cold Fusion, and Dynotune. The openers that I am talking about are the mechanical/motorized ones not the valve ones. The valve ones seem to cheaply made and they can go bad after awhile.

Well...Since at my new job that i got, they are working me more hours and I also got in increase in pay, so I am actually making money that I can use to put into my car

I also have not spent any of my tax return money and that should be around 700 and I also have like another 2k in the bank that I wont touch just in case I break my car somehow.

Now some things that I am looking to do in the future well, meaning this summer is to get a bullit suspension package which will run me around 450 and then I am going to get some Maximum Motorsports Full Length subframe connectors that will cost me 300-350 for everything installed. When Christmas rolls around I am going to see what I can do for getting some wheels and some good drag radials and then I think I will be set for now...Until I see a cheap set of heads and I am dumbass and buy them...I just dont know if I want to do an HCI because it will be a pain in the ass.
