IIRC, don't those retailers sell the pl50 for close to $75? Focalprice sells them for $55, sometimes $50 if they're having a sale or you can find a coupon. That's where I bought mine when I had them. And frankly, while they're a good buy for $50, I don't think they're worth $75
ALO lists PL50 for $55, I believe, no free shipping though. FocalPrice is definitely cheap, but customer service is generally slow and warranty will take a long time. It is what you are not paying that is what you have saved. Obviously it is up to the buyer to decide what is important..
