Bertoia vs. Bertoia knock off

I've been looking for some Bertoia barstools recently and since they are so G-D expensive new ($781 each), I've been searching craigslist for a pair of used ones. I came across a crazy site, Advanced Interior Designs, that basically is DWR knocked-off. So, here's the bottom line: Can you tell the difference between the above two barstools? (Excuse the shotty images, they are the same size in real life.) One is $781 and one is $165. I, sadly, can tell the difference and am snotty enough to care. The one on the left is the knock-off and the one on the right is the authentic Bertoia barstool. Advanced Interior Designs has tons of other items that I can't tell though, and some items are thousands of dollars cheaper, thousands!
