Food Steamer Help

Options
So since joining here and tracking my foods I've really started to become aware of the sodium levels in my foods that I eat. I've never really paid much attention to this in the past, but I figure I aught to try and get it down to the point where I am not having my WHOLE day's budget in one meal!

I think steaming veggies/meats might make a tasty enough meal that's pretty low in sodium so I've been looking at food steamers...only thing is, I can't seem to find one that I know is BPA free for sure? normally i wouldn't mind some amount of BPA except that in a food steamer you are heating the plastic up which is exactly when you need to worry about things like this. :S

anyone found a good one they know is BPA free? [no, i don't want to use the stove - that'd add like 30minutes to get the water boiling]

thanks!
