Not quite true, Jeff. I bought 3 flat files last year from Laguna Beach for $100 each. I drive a Sequoia, so I did 2 round trips over two weekends to pick them up. Brand new. The larger size. Like everything else, it's all about looking and waiting for the right ones to come along. If you're in a rush, you pay. If you're patient, you get a deal.
I already need 3 or 4 more so I'm looking again.
