Bottles are recertified (and a really old flea-market 5-lb CO2 extinguisher too, had it recharged once it passed). Just have to go pick them up tomorrow

Now... what are people paying for nitrous oxide these days?

There is only one speed shop in my town and they want $75.00 to fill each 10-lb bottle
I know prices have gone up since the last time I paid $35 (admittedly 25 years ago) but that seems awfully high.
