Ikea's MOLGER mirror is similar.

I would look at CB2, IKEA, or west elm for some similar modern mirrors that may be less expensive.

Also take that picture and put it in google search, or search "rectangular modern mirror" or something and see what you find.

Those are really nice. You can check Overstock.com and HomeDecorators.com to see if you fall in love with something less expensive.

I'm in love with these loft mirrors from Room & Board but they're $$$:

I would love to find something similar for cheaper price, if possible.
Has anyone seen something similar online or at other furniture/home decoration retail stores?
