A couple of thoughts:

1. Single stage regulators are cheap...and not as accurate as a 2
stage....You paid 2 stage money....The one stage would show an accurate
reading if you let the output bleed quickly while setting the gauge..

99% of planted aquarists who use compressed-CO2 setups are using
single stage regulators. They do the job perfectly fine. And while
$65.00 is a little high for a cheap reg, it's way below the cost of a
dual-stage regulator. And the dual stage regs are overkill for our
purposes.

3. I hate trade-ins for things like this....It may be OK for a cutting
rig that has all valves shutoff most of the time....but who wants a
leaky old bottle

You are not going to get a "leaky" bottle. And for cutting, if the
valves were shut-off, you'd still have the leak, if it was the bottle.

The only downside to trade-in tanks are the physical appearance.
