Sandy, the bad oils to cook with are the ones that are high in
polyunsaturated fat (like corn, safflower, Wesson...), because they denature in the heat and turn into trans fat. Olive and nut oils are high in
monounsaturated fat, the good kind.
Beans: +1 what Tail and Raynes said. Plus, once your digestive system gets used to dealing with beans, that problem goes away.
Ebay has a ton of analog cases. Stick a thin piece of fabric or foam in there and you're good to go. Most of the styles are for the 100s (100mm long). A 120s case will hold fully assembled 78mm batts + regular cartos, like this:
If you need something longer (like for X2s), opera wallets have the same closing mechanism, but you'd have to cut out the guts (credit card pockets, etc.), and attach something to hold the batts down (like elastic) or play with cutouts in foam. I know they make cases like that for eGos (about the same size as X2s) in China, but finding someone who actually sells them might be tough. But I'm lazy. I'm looking for
something that would hold the batts with the tanks attached, and if it could hold a couple, then the charging cable and juice could just stay at home or in the car.
