Seems that you can get better fills just freezing the bottle and filling it. The price of a chest freezer is far less than a pump.
Do you think it would be feasable to, say, take your bottle heater out the car and use it on the mother bottle when that one starts to get low to fill better?

I think just filling a styrofoam cooler with ice and water would work pretty well. Those things can get really cold and the cost would be relatively cheap. Provided you have a freezer with an ice machine.

No way of telling how "cold" a foam ice chest is with ice. Also, the idea of a bottle heater out of the car will have little effect on a 56 lb bottle. After many hours of trying to heat it, you'll find the aluminum will dissipate the heat faster than you can warm it. HOWEVER.. wrapping it in a water heater blanket would be a great idea. 65 deg is a little chilly. I think it's 80 deg gets you around 950 psi. (someone correct my figures if they're off)

My local nitrous filler has an ancient electric pump that he can put 10# in my bottle at any temp. He says its one of the most reliable ways of ensuring a true fill. Ive been trying to scope myself out one, so I could just start buying mother bottles, but have had no luck.
This also ensures a complete empty of the mother bottle, so there isnt any wasted gas.

this is true...we use a big *** meat freezer filled with slushy ice water,,usually can fill a 10# inside 40 minutes....in the ice longer i can get 11-12#'s in a 10#er...

I just got a 65lb bottle for $190 at praxair. Plus I found two pump manufactures to order a pump thru. I can get a new pump for $410. But because of the modification it is a 3-6 week wait.

When I had nitrous on my talon I froze my bottle. I would stick it in the freezer the night before. Splash a little water on it so it had a nice lair. The shop I had it filled up at charged a set rate for a 10lb bottle. So I would get barely over 11lbs in a 10lb bottle and it would cost me the same. It was pretty cheap also. I believe about 25 bucks for a 10lb bottle.
