Filling with nitrogen

Expensive.
My set up costs:
Bottle of Nitrogen is about $100
A set of victor guages that the refirgeration guys use is about $110. 0-600
PSI on the low side.
$13 for the gooseneck to fit the schrader valve and $25 to have a long
hi-pressure hose made.

Keep in mind that it a takes high pressure to force the schrader's needle
valve open.

Ok, today I got the nitrogen bottle, it was about $100 for 40 (liters?).
The regulator is high side is 0-4000 psi, low side 0-200 PSI. Is this
enough, or do I need to exchange that, and what pressure is required?
Standard pressure hoses, as I am sure you are aware, are only good
up to 200psi.

Thanks for all the hints.
