When I bought my ETRSi, I made sure it was one with the folding WLF because the price on them was crazy for what they were. Funny thing, at the time the WLF was selling for ~$150, and I got my camera (with PE 50mm) for $250. I did the exact same thing when I bought into a GS-1, again because the WLF sells for what I consider to be crazy money. I have, on rare occasion, seen the ETR WLF list for $100, but it gets snapped up quickly, so I don't thing there are sources for cheaper, you just need to decide what you're willing to pay, and just keep on the lookout until you find one. If you need one and can't wait, then you're stuck paying the common prices.
