How have your cans from Sportsmans Guide worked out? The one caution I'd heard about the cheaper Chinese cans is that they are susceptible to rusting on the inside, especially with ethanol-containing fuels, and that they use rolled seams rather than a full seam weld so are more prone to leaking if they get knocked around.
I've been very pleased with my jerry cans so far. There is not one bit of odor with them.
