Default Recommendation on a Gas detector (Sniffer) for the DIY homeowner

I am ready to purchase a gas detector. I had a couple very slow leaks in my gas lines that took me quite a while to diagnose with the ole bubble/soap trick. It may just be my mind playing tricks, but I sometimes think I still smell gas, but nobody else does. I would like to ask you HVAC guys and anyone else that uses a gas detector what you would recommend? Just something that is accurate and constructed with quality. Not looking to spend a fortune, maybe $100 to $200 if possible. Thanks

If its that small of a leak I just use a lighter. It will just make a small flame.

X2
I do this.

However if it is not a small leak we will deny we ever gave you advice.

Seriously though I find the lighter method best for finding small leaks. Make sure to put out the flame once it ignites.

Btw don't use teflon tape. Use pipe dope. Don't get the dope in the tubing. Only use pipe dope on threads of the pipe. NOT on brass compression or flare fittings!!!

I've heard people say not to use tape. I have no idea why. It works just fine. I use a lazy flame on my torch to check for leaks.

The yellow tape is thicker and required by code in some states. Michigan is not one of them. Regular tape works fine. I just use pipe dope. Household gas lines have less than a half psi, and don't take much to seal. Back when fittings were made in the USA, plumbers didn't use any sealant, only a few drops of oil.
Inspectors here want to see a 5psi air test hold for 15 minutes.
