Lamps Plus is always having sales...

Check out "mercury glass" on ebay. You might be able to score a cheap piece that could be converted to a lamp.

Different scale, but nice, and on sale:

Here's one on eBay for $25, but you'd need to replace the hideous shade

You could also, if you wanted to go the Ikea route (I know, I know) you could grab a lamp from there that is similar in shape and spray paint the base in a silver. DIY the lamp! :)

They have a chrome base lamp:

This Silver Ball Lamp could work, and you can always request a more neutral shade.

Ditto for painting it in silver on this:

Krylon makes a terrific mirror paint that is designed to be sprayed on the inside of clear glass--and it looks amazing. You'd never guess that it's spray paint! So you could take any inexpensive clear glass lamp and make it look just like this.

I saw a shiny lamp at EQ3 a while ago.

KRYLON!

I just saw something like that on clearance at Target yesterday. Can't find it on the site though...

I saw the lamps that at Target that Linnealoves mentioned. They are marked down to $29. They do look pretty similar to these.

I think this is the EQ3 lamp mentioned above:

Great if you want a dark lampshade! It's listed at $159.99.
