I don't even want to know how you tested the sensor from Sharper Image.

Anyway, do a search for "gas leak detector" (try with and without the quotes). You'll get plenty of ready-made products, but also a number of hits to component-level sensors. Several are for a variety of cumbustible gasses, with and without odorizers.

Also look up the UEI CD100A, a low-cost consumer-level detector unit. Maybe you can hack into it.

Talk to a local utility that does any kind of underground vault work (electric, gas, water, cable) They will typically have a guy that calibrates their units and tests them regularly. A few kind words may get you an unofficial test run.
