I use gallons of the stuff. The health concerns were due to the erucic acid content, especially amongst the anti-canola brigade as canola (rapeseed) oil contains a whack of it as well - rapeseed being related to mustard.
However I think that's now been consigned to the "aluminium pans will give you Alzheimers" category.
My seasoned oil that I use at the moment is:
50% Rice Bran Oil
25% Mustard Oil
25% Indian butter ghee
Fry a finely sliced onion until caramelised, then remove the bits. I keep it in a 750ml old beer bottle with a cork in the neck and use with gay abandon ;D
