Nitrous newbie

OK, is this a good deal on a NX kit: #20920 full bottle $565
blow down tube $24
gauge $47
injector thing $2
----------------------
total $ 660

I was told the window swith isn't nessasary because the kit comes with a WOT switch. Is this true? So, is this all I really need or is there some other things I'm gonna need?

I've got a link in my sig that might help. The WOT switch and the window switch are very different things...

try ebay they have some cheap nx kits

but that price doesnt sound bad at all
