If you plan to use any of these as lunchboxes, it's worth considering whether or not they can be microwaved.

I was looking into some kind of tiffin solution for just bringing lunch to work. The DWR ones looked tempting, but the price tag not so much.

I settled on the To-Go Wear 2 tier tiffin-like stainless steel thing at reusablebags.com and love it. It's not for microwave-requiring foods, but it's ideal for salads, grain salads or anything you don't mind eating at room temp. And far more affordable.

Cost Plus has a couple of similar food containers too.

These are even better cuz their stainless

If you have any friends from India, you can ask them to get you the stainless steel tiffin box on their next trip to India. They cost around $5 there. Make sure you ask your friend for a thicker gauge of steel, the bowls made of thin steel CAN start cracking open near the edge.
In India, we carry our lunches in these tiffin boxes right from elementary school. You also get tiffin boxes that have the plastic thermal cylindrical case that you put the tiffin box in to keep you food warm/cold.

You can get the stainless steel tiffins from any Indian food / groceries supply store. For less than $20 usually!

I own the Bento Picnic Box from Plastica, I love it, but you can not microwave it. Although it is dishwasher safe.

call me crazy, but the $85 pricetag doesn't seem THAT extravagant to me
