I recently bought a Dry kit off ebay for $279.95 with a 5lb bottle for space saving and I must say, It's a great kit. well packaged it includes like 10 nozzles for adjustable spray up to 100HP. I knpw we are not supposed to link ebay stuff but just look under nitrous kits. I can't remember the brand off hand (brain fart). I know the ebay user name is catdaddy.
